Last September, as part of its annual conference with the United States Central Command, the Saban Center for Middle East Policy at the Brookings Institution conducted a day-long simulation of a confrontation between the United States and Iran arising from a hypothetical scenario in which the Syrian opposition had made significant gains in its civil war and was on the verge of crushing the Assad regime.  

The simulation suggested that, even in the wake of President Rouhani’s ascension to power and the changed atmosphere between Tehran and Washington, there is still a risk of misunderstanding and miscalculation between the two sides.

This new Middle East Memo examines the possible U.S. foreign policy lessons that emerged from this crisis simulation, and stresses the importance of communication, understanding the Saudi-Iran conflict and the difficulty in limited interventions.

• Hard Road to Damascus: A Crisis Simulation of U.S.-Iranian Confrontation over Syria

When Iran and the P5+1 signed a deal over Tehran’s nuclear program last July, members of Congress, Middle East analysts, and Arab Gulf governments all warned that the agreement would prompt Iran’s rivals in the region to race for the bomb.

In a report that Bob Einhorn and I released this week, we assessed this risk of a so-called proliferation cascade. We look at four states in particular—Saudi Arabia, the United Arab Emirates, Egypt, and Turkey—and Bob briefly explores each case in another blog post out today. In the paper, we argue that although the likelihood of a proliferation cascade in the Middle East is fairly low, and certainly lower than a number of critics of the Iran deal would have you believe, it is not zero. Given that, here are eight steps that leaders in Washington should take to head off that possibility:

1. Ensure that the JCPOA is rigorously monitored, strictly enforced, and faithfully implemented;
2. Strengthen U.S. intelligence collection on Iranian proliferation-related activities and intelligence-sharing on those activities with key partners;
3. Deter a future Iranian decision to produce nuclear weapons;
4. Seek to incorporate key monitoring and verification provisions of the JCPOA into routine IAEA safeguards as applied elsewhere in the Middle East and in the global nonproliferation regime;
5. Pursue U.S. civil nuclear cooperation with Middle East governments on terms that are realistic and serve U.S. nonproliferation interests;
6. Promote regional arrangements that restrain fuel cycle developments and build confidence in the peaceful use of regional nuclear programs;
7. Strengthen security assurances to U.S. partners in the Middle East; and
8. Promote a stable regional security environment.

Taken together, these steps deal with three core challenges the United States faces in shoring up the nonproliferation regime in the region.

The first is that the central test of nonproliferation in the Middle East will come from how the JCPOA is believed to be meeting its core objective of preventing Iranian nuclear weapons development and Iranian establishment of regional hegemony. It cannot be stressed enough that the decision to pursue nuclear weapons by any state, including those in the region, starts with a sense of vulnerability to core security threats and an inability to address those threats through any other means. The history of nuclear proliferation is one of tit-for-tat armament in the face of overriding security imperatives. Both finished and aborted nuclear programs bear the hallmarks of a security dilemma impelling states to make the political, economic, and security investments into nuclear weapons.

This is no less true for countries across the region than for Iran. To the extent that the overall security environment can be stabilized, there will be less impetus for any Middle Eastern state to develop nuclear weapons. The United States should focus on:

• Fully implementing and enforcing all sides of the JCPOA (nuclear restrictions, transparency, and sanctions relief);
• Creating a strong sense of deterrence toward Iran, manifest most clearly in the passage of a standing Authorization to Use Military Force if Iran is determined to be breaking out toward acquisition of a nuclear weapon;
• Providing security assurances and backing them up with the mechanisms to make them actionable like joint exercises, logistical planning, and cooperation with a range of regional and extra-regional actors; and,
• Working to promote a more stable regional environment by seeking the resolution of simmering conflicts.

But, these latter two factors also point to another resonant theme in our research: the need for the United States to be a player. After decades of involvement in the region, the United States has yet to settle upon the right balance between involvement and remove. Yet, establishing this equilibrium is essential. States in the region need predictability in their affairs with the United States, including knowing the degree to which our assurances will stand the test of time.

States in the region need predictability in their affairs with the United States, including knowing the degree to which our assurances will stand the test of time.

In part for this reason, the United States should not only pursue deeper security relationships, but also civil nuclear cooperation with interested states throughout the region. Such a relationship both ensures a closer link between the United States and its partners and discourages the spread of enrichment and reprocessing technology by disincentivizing countries from “going it alone.” In the Middle East, the United States would need to find a formulation that offers some flexibility (such as by building in language that would permit the United States to terminate any nuclear cooperation arrangements in the face of sensitive fuel cycle development by the other side).

The United States should also share intelligence more closely with its partners in the region. This is helpful in the short term, of course, but also helps the United States understand the mindset of and intelligence picture of its regional partners in a broader sense. It also helps leaders in Washington address concerns brought about by unfounded rumors or speculation as to Iran’s intentions or capabilities.

Changing how we do business

Even more important than how the JCPOA was negotiated will be how we transition from its restrictions and transparency mechanisms into a new world in 15 to 20 years. 

The United States seek to incorporate elements of the JCPOA into normal international monitoring practices and should negotiate new arrangements to help govern the future development of nuclear technology in the region. 

To achieve the former, the IAEA will need to make some changes to how it does business. For example, the IAEA determines how best to implement its monitoring mission, contingent on acceptance by the country being inspected. The United States and its partners should work with the IAEA (and other countries with significant nuclear activities) to make some parts of the JCPOA standard operating practice, such as online monitoring of enrichment levels. Other elements of the JCPOA may require agreements at the IAEA and beyond for how nuclear-related activities, including those that could have value for nuclear weaponization, are handled. It might be hard to get agreement, not least because there is clear language in the JCPOA that states that it will not be seen as a precedent for future nuclear nonproliferation efforts. However, it should still be the ambition of the United States to make such steps part of the norm. 

A far more difficult lift would be organizing a regional approach to the nuclear fuel cycle. This is not the same as creating a multilateral fuel cycle, though some elements that approach would be helpful. Rather, the United States should find ways to craft regional agreements or, failing that, moratoria on aspects of the fuel cycle that others in the region would find threatening. It would be easier to negotiate constraints some aspects than others. For example, spent fuel reprocessing is rare in the Middle East, with only Israel having been known to do it to a significant degree. It may therefore be an attractive first place to begin. Enrichment would be altogether more difficult, but it may be possible to convince states in the region to forego the expansion of their enrichment programs beyond their status quo. For Iran, it would continue to possess uranium enrichment but with constraints that limit the utility of this program for weapons production; its incentive would be to avoid creating the rationale for regional competition. For other countries in the region, it would involve holding off on enrichment, but also on the financial and political investment enrichment would involve—as well refraining from creating a security dilemma for Iran that could produce miscalculation in the future.

While some of these recommendations are more challenging (and may prove impossible), others are potentially easier. By taking a multifaceted approach, the United States increases the chances that no further weapons of mass destruction proliferate in the Middle East down the road.

Editors’ Note: The phenomenon Donald Trump has created has become something larger than him, and something far more dangerous, writes Bob Kagan. This phenomenon has arisen in other democratic and quasi-democratic countries over the past century, and it has generally been called “fascism.” This piece originally appeared in The Washington Post.

The Republican Party’s attempt to treat Donald Trump as a normal political candidate would be laughable were it not so perilous to the republic. If only he would mouth the party’s “conservative” principles, all would be well.

But of course the entire Trump phenomenon has nothing to do with policy or ideology. It has nothing to do with the Republican Party, either, except in its historic role as incubator of this singular threat to our democracy. Trump has transcended the party that produced him. His growing army of supporters no longer cares about the party. Because it did not immediately and fully embrace Trump, because a dwindling number of its political and intellectual leaders still resist him, the party is regarded with suspicion and even hostility by his followers. Their allegiance is to him and him alone.

And the source of allegiance? We’re supposed to believe that Trump’s support stems from economic stagnation or dislocation. Maybe some of it does. But what Trump offers his followers are not economic remedies—his proposals change daily. What he offers is an attitude, an aura of crude strength and machismo, a boasting disrespect for the niceties of the democratic culture that he claims, and his followers believe, has produced national weakness and incompetence. His incoherent and contradictory utterances have one thing in common: They provoke and play on feelings of resentment and disdain, intermingled with bits of fear, hatred and anger. His public discourse consists of attacking or ridiculing a wide range of “others”—Muslims, Hispanics, women, Chinese, Mexicans, Europeans, Arabs, immigrants, refugees—whom he depicts either as threats or as objects of derision. His program, such as it is, consists chiefly of promises to get tough with foreigners and people of nonwhite complexion. He will deport them, bar them, get them to knuckle under, make them pay up or make them shut up.

That this tough-guy, get-mad-and-get-even approach has gained him an increasingly large and enthusiastic following has probably surprised Trump as much as it has everyone else. Trump himself is simply and quite literally an egomaniac. But the phenomenon he has created and now leads has become something larger than him, and something far more dangerous.

[T]he phenomenon he has created and now leads has become something larger than him, and something far more dangerous.

Republican politicians marvel at how he has “tapped into” a hitherto unknown swath of the voting public. But what he has tapped into is what the founders most feared when they established the democratic republic: the popular passions unleashed, the “mobocracy.” Conservatives have been warning for decades about government suffocating liberty. But here is the other threat to liberty that Alexis de Tocqueville and the ancient philosophers warned about: that the people in a democracy, excited, angry and unconstrained, might run roughshod over even the institutions created to preserve their freedoms. As Alexander Hamilton watched the French Revolution unfold, he feared in America what he saw play out in France—that the unleashing of popular passions would lead not to greater democracy but to the arrival of a tyrant, riding to power on the shoulders of the people.

This phenomenon has arisen in other democratic and quasi-democratic countries over the past century, and it has generally been called “fascism.” Fascist movements, too, had no coherent ideology, no clear set of prescriptions for what ailed society. “National socialism” was a bundle of contradictions, united chiefly by what, and who, it opposed; fascism in Italy was anti-liberal, anti-democratic, anti-Marxist, anti-capitalist and anti-clerical. Successful fascism was not about policies but about the strongman, the leader (Il Duce, Der Fuhrer), in whom could be entrusted the fate of the nation. Whatever the problem, he could fix it. Whatever the threat, internal or external, he could vanquish it, and it was unnecessary for him to explain how. Today, there is Putinism, which also has nothing to do with belief or policy but is about the tough man who singlehandedly defends his people against all threats, foreign and domestic.

Successful fascism was not about policies but about the strongman, the leader (Il Duce, Der Fuhrer), in whom could be entrusted the fate of the nation.

To understand how such movements take over a democracy, one only has to watch the Republican Party today. These movements play on all the fears, vanities, ambitions and insecurities that make up the human psyche. In democracies, at least for politicians, the only thing that matters is what the voters say they want—vox populi vox dei. A mass political movement is thus a powerful and, to those who would oppose it, frightening weapon. When controlled and directed by a single leader, it can be aimed at whomever the leader chooses. If someone criticizes or opposes the leader, it doesn’t matter how popular or admired that person has been. He might be a famous war hero, but if the leader derides and ridicules his heroism, the followers laugh and jeer. He might be the highest-ranking elected guardian of the party’s most cherished principles. But if he hesitates to support the leader, he faces political death.

In such an environment, every political figure confronts a stark choice: Get right with the leader and his mass following or get run over. The human race in such circumstances breaks down into predictable categories—and democratic politicians are the most predictable. There are those whose ambition leads them to jump on the bandwagon. They praise the leader’s incoherent speeches as the beginning of wisdom, hoping he will reward them with a plum post in the new order. There are those who merely hope to survive. Their consciences won’t let them curry favor so shamelessly, so they mumble their pledges of support, like the victims in Stalin’s show trials, perhaps not realizing that the leader and his followers will get them in the end anyway.

A great number will simply kid themselves, refusing to admit that something very different from the usual politics is afoot.

A great number will simply kid themselves, refusing to admit that something very different from the usual politics is afoot. Let the storm pass, they insist, and then we can pick up the pieces, rebuild and get back to normal. Meanwhile, don’t alienate the leader’s mass following. After all, they are voters and will need to brought back into the fold. As for Trump himself, let’s shape him, advise him, steer him in the right direction and, not incidentally, save our political skins.

What these people do not or will not see is that, once in power, Trump will owe them and their party nothing. He will have ridden to power despite the party, catapulted into the White House by a mass following devoted only to him. By then that following will have grown dramatically. Today, less than 5 percent of eligible voters have voted for Trump. But if he wins the election, his legions will comprise a majority of the nation. Imagine the power he would wield then. In addition to all that comes from being the leader of a mass following, he would also have the immense powers of the American presidency at his command: the Justice Department, the FBI, the intelligence services, the military. Who would dare to oppose him then? Certainly not a Republican Party that laid down before him even when he was comparatively weak. And is a man like Trump, with infinitely greater power in his hands, likely to become more humble, more judicious, more generous, less vengeful than he is today, than he has been his whole life? Does vast power un-corrupt?

This is how fascism comes to America, not with jackboots and salutes (although there have been salutes, and a whiff of violence) but with a television huckster, a phony billionaire, a textbook egomaniac “tapping into” popular resentments and insecurities, and with an entire national political party—out of ambition or blind party loyalty, or simply out of fear—falling into line behind him.

Editor's note: This piece originally appeared in the Wall Street Journal's Washington Wire on July 11, 2016. Theresa May has since succeeded David Cameron as UK prime minister.

Theresa May is poised to become Britain’s next prime minister on Wednesday. This means there is a reasonable chance the post-Brexit whirlwind of U.K. politics will quiet somewhat. Here are seven things that stand out about the next PM:

1. Her experience. Ms. May has been in the top ranks of British politics for almost two decades. She is one of the longest-serving home secretaries, overseeing domestic security, law and order, and immigration. With the exception of Michael Gove, who was knocked out early in the contest, she was by far the most experienced candidate in the race.

2. Her resilience. Ms. May is what Americans call a tough cookie. When I was in government, she was the Cabinet minister with whom David Cameron least liked to tangle. When Ms. May said no, she meant no. This did not always lead to perfect policy outcomes, of course. But few in Westminster doubt her strength.

3. Modernizing instincts. As the Conservative Party’s first female chairman, Ms. May pointed out in 2002 that to many voters the Tories were seen as the “nasty party” and that reform was essential. She helped to lay the ground for David Cameron to emerge as a new, more moderate face of the Conservative Party. Ms. May was also one of the first senior Conservatives to back same-sex marriage.

4. She backed Remain. As the only leadership candidate who was on the losing side of the Brexit vote, she is, paradoxically, well-placed to unite the Conservative Party in parliament. Most Tory MPs were, like Ms. May, in the Remain camp. But she was a lukewarm Remainer and has a history of being skeptical of European institutions–including the European Convention on Human Rights–which will endear her to Brexiteers. Already she has made it clear that “Brexit means Brexit” and that she will only trigger Article 50, which governs the process by which an EU member exits, when she has her negotiating position worked out. So far, so good. (Particularly for those worried about market volatility and the U.K. economy in the wake of the June 23 referendum.)

5. Government stability. Given her strong support among parliamentary colleagues, Ms. May is not likely to feel any need to trigger an emergency general election. Instead, she can make the case that the U.K. needs a stable government during the lengthy Brexit negotiations to come (and she’ll be right). Labour politicians calling for an election are whistling in the wind, especially given their own leadership civil war.

6. Gender issues and non-issues. Theresa May is about to become the U.K.’s second female prime minister and there has been refreshingly little commentary on her gender. The only real exception was the row caused by her opponent Andrea Leadsom, who clumsily implied in a recent interview that not being a mother made Ms. May less qualified. (Ms. Leadsom apologized shortly before dropping out of the contest.) If Labour MPs manage to dislodge their leader, Jeremy Corbyn (an outcome that may be decided in court), the favorite to succeed him is Angela Eagle, who is married to a woman.

7. Redressing the class balance. The United Kingdom has been run by posh people, since, well, forever. But David Cameron’s crowd was a particularly upper-crust bunch, mostly educated at private schools. Ms. May, by contrast, went to a comprehensive high school (in American English, a public school). To the extent that there is need for more class diversity among governing elites, this is another piece of good news.

None of this alters the disastrous economic implications of the Brexit vote. But by turning to May, the Conservatives will be better prepared to secure a period of stable government, with a little more class and gender diversity thrown in for good measure. That’s about the best one could hope for.
