North Korea and Iran may deem the cost of not talking to Trump too high, which implies that they would engage him—but resisting surrender is their priority. This means that maximum pressure as a guiding strategy will have diminishing value over time. Indeed, if the president’s national-security team continues with maximum pressure in pursuit of surrender, they’ll encounter resistance from Iran and North Korea. Waiting out the Trump presidency or hoping for the policy to implode could become the two countries’ preferred option.

What North Korea is looking for is a step-by-step diplomatic process in which the United States offers concessions ranging from a declaration of peace on the Korean Peninsula to the lifting of economic sanctions. Instead, Trump’s national-security team is demanding full denuclearization before offeri ng anything up in return. That looks to be what Washington has in mind for Iran as well.

Faced with this reality, Pyongyang or Tehran c ould see a benefit in resisting Washington’s pressure strategy. Kim Jong Un is willing to engage in summitry but has yielded little ground on the demand that he unconditionally relinquish his nuclear and missile programs. Iran, for its part, sees little point in going as far as North Korea has. Talking to Trump would effectively kill the international nuclear deal it signed in 2015, which the United States left last May; Trump likely expected that Iran would follow suit, and that he would sign his own deal with Iran. Washington is now ratcheting up economic pressure on Iran, and warning other signatories against doing business with Iran.

Iran is not reaping any economic benefits inside the deal, but it is unlikely to get any outside the deal either, even if it were to talk with Washington. But if Iran did abandon the deal, it would give up the hard-won right to a nuclear program, which is enshrined in the accord. That is likely why Iran’s President Rouhani said last week that the United States must rejoin the deal before he would talk with President Trump. His thinking: If the Trump administration brought the United States back into the deal, it could no longer look to the Libya model as the goal, and would have to negotiate from the existing baseline of the 2015 deal.

Of course, it’s not only North Korea and Iran that bear the brunt of maximum pressure. This is a policy levied at the entire international community, which will likely resist the policy, potentially leading to its implosion. Indeed, if America’s isolation at last week’s United Nations Security Council special session, in which it tried to rally support for its policy on Iran, is any indication, maximum pressure has little international backing. While the maximum-pressure strategy received initial support in China and South Korea, that support began to wane after Pyongyang agreed to the Singapore summit. The United States is also threatening its European allies with punishment if they facilitate business with Iran, and India is being forced to forego its investment in the port of Chabahar in Southeast Iran, a gateway to Afghanistan and Central Asia that allows India to balance China’s regional influence. U.S. pressure, meanwhile, has already led Europe, China, and Russia to explore ways to circumvent U.S. sanctions.

What all this means: The wanton use of maximum pressure by Washington is likely to create a world in which the United States is unable to exercise much pressure at all.
