Indeed, it is easier to see the collisions that are coming than to see how we get off this road before the shooting starts.

After "de-certifying" the nuclear agreement, signed by all five permanent members of the Security Council, Trump gave Congress 60 days to reimpose the sanctions that it lifted when Teheran signed.

If Congress does not reimpose those sanctions and kill the deal, Trump threatens to kill it himself.

Why? Did Iran violate the terms of the agreement? Almost no one argues that – not the UN nuclear inspectors, not our NATO allies, not even Trump's national security team.

Iran shipped all its 20 percent enriched uranium out of the country, shut down most of its centrifuges, and allowed intrusive inspections of all nuclear facilities. Even before the deal, 17 U.S. intelligence agencies said they could find no evidence of an Iranian nuclear bomb program.

Indeed, if Iran wanted a bomb, Iran would have had a bomb.

She remains a non-nuclear-weapons state for a simple reason: Iran's vital national interests dictate that she remain so.
