Matthew Continetti explains at National Review Online why he’s glad to see President Trump dump the Obama-era nuclear deal with Iran.

The deal, announced to such fanfare in July 2015, did not live to see its third birthday. And for that, I am grateful.

Why? Because the president said not only that America will be leaving the accord. He declared that the period of waxing Iranian influence in the Middle East is at an end. The deal financed several years of Iranian expansion through Shiite proxies in Iraq, Syria, Lebanon, and Yemen. By reimposing sanctions, President Trump will weaken an already ailing Iranian economy. The Iranian currency, the rial, has plummeted in recent weeks. Inflation is rampant. The financial system is corrupted, dysfunctional. Strikes are proliferating and often turn into displays against the government. This is a situation the United States should seek not to mitigate but to exacerbate.

Removing ourselves from the deal puts Iran on the defensive. Its people and government are divided and uncertain how to respond. Its leverage is minimal. Iranian citizens have seen their leaders use the money from the deal not to improve the economic lot of the average person but to fund the military, IRGC, and other instruments of foreign adventurism. Implicit in the deal was recognition of the Islamic regime as a legitimate member of the so-called international community. President Trump has rescinded that recognition and the standing that came with it.
