More than six months ago, Donald Trump declared that the U.S. would no longer abide by the terms of the 2015 agreement in light of Tehran’s violations of it. As Fred Fleitz explains, events have vindicated the U.S. decision:

Trump’s withdrawal from the Joint Comprehensive Plan of Action (JCPOA), [as the deal is formally known], did not lead to war with Iran, as many critics predicted. Instead, Iran is far more isolated than it was when President Trump assumed office. The United States has worked to unite its Middle East allies, especially Israel and Saudi Arabia, against Iran and, in Warsaw this month, will co-chair an international conference with Poland on the threat from Iran. Iran’s economy is under unprecedented pressure thanks to re-imposed U.S. sanctions, especially oil sanctions, with negative 1.5-percent growth in 2018 and an expected negative 3.6-percent growth in 2019. Iran’s current year-on-year inflation rate through last month was 40 percent.

Some Trump critics predicted that any effort by the president to reimpose U.S. sanctions lifted by the JCPOA would have little effect, since other parties to the agreement—in particular the EU, Germany, France, and the UK—would not follow suit. But numerous European companies have resisted pressure from their governments to defy the re-imposed U.S. sanctions. On January 31, European leaders announced a special finance facility to help European firms skirt U.S. sanctions on Iran, but that initiative is months behind schedule, and few experts believe it will work. . . .

Before the U.S. withdrawal, JCPOA critics made strong arguments about the accord’s weaknesses, especially Iran’s refusal to allow International Atomic Energy Agency (IAEA) inspectors access to military sites. The lone exception is the Parchin military base, [where] the IAEA obtained evidence of covert nuclear-weapons work. . . . JCPOA supporters rejected those criticisms, noting that the IAEA repeatedly declared Iran to be in compliance with the nuclear agreement. However, they refused to admit that the IAEA reached its compliance findings by claiming that Iranian violations were not “material breaches” and by not asking to inspect Iranian military facilities that Tehran has declared off-limits, even though they are the likely locations of covert nuclear-weapons work.

As for last week’s report to the Senate by U.S. intelligence officials, according to which the Islamic Republic has been technically complying with the deal, it ignored, among other things, evidence to the contrary released by the Mossad. Fleitz argues that deep-seated institutional bias is at play in the report.

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.
