Like me, you would—as a last effort, if nothing else worked and we had no other ability to stop a bomb—support military strikes as well. But we're not talking about military strikes against Iran's nuclear facilities and a dash to a bomb. We're talking about the question of regime change.
As I said, I support a change in the regime: a peaceful change in the regime in the way that Shirin Ebadi and hundreds of thousands of Iranians support it, which is a peaceful, secular constitution, the end of the supreme leader as an office and as a man who is responsible for brutal repression at home and gross human rights violations abroad.
If I take your argument to its logical conclusion, what you're actually saying is if we have a brutal regime, we should do nothing to change it. We should leave it in place.
