Israeli Prime Minister Benjamin Netanyahu this week offered fresh reason why the Iran nuclear deal was never good enough — namely, new proof that Tehran has been cheating on its nuclear promises for years.

Specifically, Bibi revealed the existence of a secret nuke-research site that Iran never revealed, even after it promised to suspend its nuclear program in the 2015 accord.

The photos show major activity at the site in the early 2000s — and then, more recently, the same cluster of buildings reduced to rubble. “This is the site after they understood that we were on to them,” Netanyahu explained.

Info on the facility was contained in an archive of Iranian nuclear activities that Israeli agents captured in January 2018, an intelligence coup that Israel made public that May. At which point, Bibi noted, “They tried to destroy the evidence.”

His message to the “tyrants of Tehran”: “Israel knows what you’re doing … and will continue to expose your lies.”

His message to the rest of the world: Iran’s “consistent pattern of lies, deception and violations” about its nuclear weapons program is ample reason “to join President Trump’s sanctions to exert more pressure on Iran. The only way to stop Iran’s march to the bomb . . . is pressure, pressure and more pressure.”

Critics painted Netanyahu’s announcement as a ploy heading into next week’s Israeli elections. In fact, it was an answer to Iran’s ongoing efforts to restore its privileges under the nuke deal: Just days earlier, for example, its foreign minister threatened to resume research that Tehran (supposedly) had suspended under the agreement.

He wasn’t playing domestic politics, just fighting back against Iran’s relentless drive to manipulate European and US politicians into letting it off the hook.
