When the president says that Iran won't get nuclear armaments on his watch, he's right if the ayatollahs stick by his version of the so-far unestablished rules of the Lausanne negotiations. With all the disagreement as to what's in the unwritten agreement, Obama's claim may or may not have teeth. Either way, by his own admittance Iran will eventually obtain nuclear weapons (some in his hire say it already has the capacity), just not while he's in office.
