Iran is not violating any deal with the U.S. after the U.S. declares the deal dead

The fundamental incoherence of Trump's position on the Iran deal is coming to the fore. Essentially his argument is the Iran deal sucks because it sunsets in just 15 years and that is too soon, so let's withdraw from the deal and make it sunset immediately.

Still, Trump got to tear up a deal negotiated by a black man, so I guess this still counts as a win.
