Information from the cache of document that Israeli intelligence removed from the Islamic Republic confirms two lies at the foundation of the 2015 nuclear agreement, writes Bret Stephens:

The first [lie] was Iran’s declaration to the International Atomic Energy Agency (IAEA), prior to the implementation of the deal, of the full extent of its past nuclear work. This was essential, both as a test of Tehran’s sincerity and as a benchmark for understanding just how close it was to being able to assemble and deliver a nuclear warhead.

The second lie was the Obama administration’s promise that it was serious about getting answers from Tehran. In a moment of candor, then-Secretary of State John Kerry admitted “we are not fixated on Iran specifically accounting for what they did at one point in time or another”—but then he promised Congress that Iran would provide the accounting. That was when the White House still feared that Congress might block the deal. When it failed to do so, thanks to a Democratic filibuster, the administration contented itself with a make-believe process in which Iran pretended to make a full declaration and the rest of the world pretended to believe it. . . .

So much, then, for all the palaver about the deal providing an unprecedented level of transparency for monitoring Iranian compliance. So much, also, for the notion that Iran has honored its end of the bargain. It didn’t. This should render the agreement null and void. . . . [I]t’s difficult to imagine that the IAEA can now square Iran’s 2015 declaration with what the Israelis have uncovered. Iran’s mendacity is no longer the informed supposition of proliferation experts. . . . It is . . . a matter of fact that the IAEA chose to ignore when it gave Iran a free pass under political pressure to move to implement the deal. . . .

Monday’s news is that Iran didn’t honor its end of the bargain and neither need the United States now. Punitive sanctions combined with a credible threat of military force should follow.

Analyzing the recent direct Iranian attack on Israel, and Israel’s security situation more generally, Michael Oren looks to the 2015 agreement to restrain Iran’s nuclear program. That, and President Biden’s efforts to resurrect the deal after Donald Trump left it, are in his view the source of the current crisis:

Of the original motivations for the deal—blocking Iran’s path to the bomb and transforming Iran into a peaceful nation—neither remained. All Biden was left with was the ability to kick the can down the road and to uphold Barack Obama’s singular foreign-policy achievement.

In order to achieve that result, the administration has repeatedly refused to punish Iran for its malign actions:

Historians will survey this inexplicable record and wonder how the United States not only allowed Iran repeatedly to assault its citizens, soldiers, and allies but consistently rewarded it for doing so. They may well conclude that in a desperate effort to avoid getting dragged into a regional Middle Eastern war, the U.S. might well have precipitated one.

While America’s friends in the Middle East, especially Israel, have every reason to feel grateful for the vital assistance they received in intercepting Iran’s missile and drone onslaught, they might also ask what the U.S. can now do differently to deter Iran from further aggression. . . . Tehran will see this weekend’s direct attack on Israel as a victory—their own—for their ability to continue threatening Israel and destabilizing the Middle East with impunity.

Israel, of course, must respond differently. Our target cannot simply be the Iranian proxies that surround our country and that have waged war on us since October 7, but, as the Saudis call it, “the head of the snake.”
