To mark the first anniversary of President Obama’s deal with Iran, the folks at the Foreign Policy Initiative have just published a comprehensive compilation of promises vs. results. It’s a devastating roundup.

FPI’s Tzvi Kahn notes what Obama, Secretary of State John Kerry and other top officials promised at the time would happen if the deal went through — in contrast with what we know now.

The level of willful deceit from Team Obama is horrifying. For example:

Under the deal, Obama said, “We will, for the first time, be in a position to verify all of [Iran’s] commitments.” A year later, we have less information about Iran’s nuclear activities than we did before the pact.

Washington will get full access to any military and “suspicious” location; Iran’s failure to allow it would result in a “snap back” of sanctions, said Kerry. Huh: The deal turns out to include an unprecedented arrangement that relies on Iran to “self-inspect” its Parchin military complex. Iran continues to deny access to Parchin and other key sites, citing the agreement to let it self-inspect.

Kerry insisted the deal contained “the exact same language” as UN resolutions prohibiting ballistic-missile development. Iran has since revealed a loophole that allows such development — which it’s been exploiting, while Team Obama now says it isn’t a violation. Kerry says he wants a “new arrangement” on the issue but agrees Washington is “powerless” to stop the missile program.

Obama insisted the deal left a “one-year breakout time” for Iran to get the bomb if it violated the agreement. Other experts say it’s more like seven months — and the latest International Atomic Energy Agency report omits data that makes it possible to calculate.

Iranian nuclear cooperation with North Korea would be “a gross violation . . . and we would take action,” said Kerry last year. Evidence since then shows Tehran has imported nuclear technology from Pyongyang.

Obama swore the United States would “maintain powerful sanctions” on Iran for its sponsorship of terrorism. Since then, he has opposed all congressional non-nuclear sanctions bills, and Kerry has pushed non-US banks to resume business with Iran.

Kerry vowed “we will never, ever stop” holding Iran to account for human-rights violations. Yet Washington hasn’t sanctioned Iran on a single case.

Treasury Secretary Jack Lew insisted sanctions relief would not change the level of Iran’s support of terrorism. Post-relief, Iran approved a 90 percent increase in military spending.

Obama said the deal would allow Iran “to move toward a constructive relationship with the world community.” Funny: Iran continues to threaten Israel with destruction, has launched cyber-attacks against the United States, holds Americans and other Westerners as hostages and illegally seized US sailors.

White House aide Ben Rhodes also admitted that Team Obama just spun a myth about a split within Iran between hard-liners and moderates.

Everything we’ve learned in the past year speaks to this deal as one of the biggest, most dangerous diplomatic blunders in US history. More than anything else, it will define Barack Obama’s legacy.

That’s actually what he’s always wanted — but it seems sure he’ll come to regret it.
