Yes, argues Matthew Kroenig; what’s more, it can be done without starting a war:

The first step to unwinding the Iran nuclear deal in a responsible manner is to establish a clear objective. That objective cannot be merely to punish Iran. The goal must be to reach a better deal, one that actually prevents Iran from building nuclear weapons. . . .

[O]n day one of his or her term, the new president can reinstate by executive order any sanctions that were suspended by the Obama administration. He or she can also put an immediate halt to the unfreezing of any still-frozen Iranian assets. Finally, he or she can cease the use of executive waiver authority, in order effectively to reinstate past congressional sanctions on Iran.

The next and most difficult step will be working with allies and partners to reinstate international and multilateral sanctions against Iran. Critics of this approach have argued that the rest of the world will not support continued [or renewed] sanctions, . . . but this is incorrect. It takes the United States, a global superpower, to lead on issues of nuclear nonproliferation.

Two extraordinary events demonstrate something important about Israel’s most fervent adversaries. One was a speech given at something called The People’s Forum (funded generously by Goldman Sachs), which stated, “When the state of Israel is finally destroyed and erased from history, that will be the single most important blow we can give to destroying capitalism and imperialism.”

The suggestion that this tiny state is the linchpin of a global, centuries-old phenomenon like capitalism goes well beyond anything resembling rational criticism. Even if Israel were guilty of genocide, apartheid, and oppression—which of course it is not—it would not follow that its destruction would help end capitalism or imperialism.

The other was an anti-Israel protest that took place in front of New York City’s Memorial Sloan Kettering Cancer Center, deemed “complicit” in Israel’s evils. At organizers’ urging, participants shouted their slogans at kids in the cancer ward, who were watching from the windows. Given Hamas’s indifference toward the lives of Gazan children, such callousness toward non-Palestinian children from Hamas’s Western allies shouldn’t be surprising. The protest—like the abovementioned speech—deliberately conveyed the message that Israel is the ultimate evil and its destruction the ultimate good, cancer patients be damned.

The fact that Israel’s adversaries are almost comically perverse does not mean that they can be dismissed. If its allies fail to understand the obsessive and irrational hatred that it faces, they cannot effectively help it defend itself.
