There’s no doubt that the catastrophic Obama-Iran nuclear deal, which flooded the Iranian regime with hundreds of billions of dollars in cash and sanctions relief, directly contributed to the recent attacks.

The deal didn’t just provide Iran with resources it poured into its military; it also created an incentive for the international community to ignore Iranian aggression for the sake of preserving the deal, emboldening the Iranians to launch exactly these sorts of attacks....

President Trump’s courageous decision to withdraw from the nuclear deal and implement a strategy of maximum pressure against Iran was the single most important national security decision of his presidency. Allowing these sanctions to expire would undermine all of that.

Meanwhile, we must continue to pressure the Iranian regime economically. Our maximum-pressure strategy against Iran has proven predictably powerful despite dire warnings from the Iran echo chamber that it wouldn’t work. Fact is, our economy dwarfs Iran’s, and the dollar is the global currency. If we have the will, we can cut off Iran from the global financial system, forcing third-party actors to choose between us or them.
