A non-physicist opines that Iran posed 'no imminent threat', the timescales for nuclear weapons and the timescales of a thug pulling a knife on you in the street are enormously different. A non-physicist doesn't fully comprehend the threat and the imminence of this threat which Iran posed, and resigns? That's a win-win: he believes he did the right thing, while the system continues to deconstruct Iran's nuclear and ballistic development facilities.
