It's this kind of insane rhetoric that makes Iran's efforts to develop nuclear weapons different from Irael's (or any Western nation's) nuclear deterrent. One wonders whether Ahmadinejad says these things because he truly believes them, because he knows he can get away with them, and/or because he desires to show "strength" to other Middle Eastern leaders. Whatever.
The point remains that in supposing that Iran has a "right" to develop nuclear weapons because other nations possess them, the Left is as usual creating a moral equivalence between Western nations that act to defend themselves and rogue states that desire to destroy us. To say that Israel will be "uprooted," in whatever context, is tantamount to a declaration of war.
The only question is, when will we start listening?
