We genuinely hope Iran’s rulers react seriously to President Donald Trump’s letter urging them to come to a rapid agreement to abandon their nuclear-weapons programs.

That means not trying to drag out talks while they rush to the atomic “finish line,” nor playing delaying games like insisting that existing sanctions get lifted before they’ll negotiate.

Trump was quite clear: Tehran tyrants need to offer up fully-verifiable proof that their nuke quest is stopped, or Washington (and Jerusalem) will stop it for them — and the clock is ticking down on them.

The best proof is for the Iranians to welcome Americans in to destroy the existing facilities, since if they’re not invited they’ll have to use force, which will do a lot more damage.

Conventional Western analysis of these issues quickly mires down in discussion of imaginary “moderate” and “hard line” factions in the Iranian regime, and how we need to navigate among them trying to strengthen the hands of the supposed good guys: That (plus a host of other delusions) is what produced the worse-than-worthless Obama nuclear deal with Iran.

Trump wisely avoided that by writing directly to the only real decision-maker, Supreme Leader Ali Khamenei.

Our president has been beyond clear here: “We’re not going to let them get a nuclear weapon,” he said last month.

And he told reporters Friday, “We’re down to the final moments”; “something is going to happen very soon, very, very soon” — plainly meaning: Either Tehran agrees to do what’s necessary so “we can have a peace deal,” or “we have to go in militarily.”

Listen to him, Mr. Supreme Leader; you can talk about the lifting of sanctions once you’ve stopped the nuclear clock.
