Andy, there's an enormous difference between threatening to wipe out an entire country or people (Ahmadenijad has threatened as much) and threatening to topple a regime. Please see the difference between the two. Also, considering the recent Green revolution which was brutally put down, Iran's support of Assad in Syria during the civil war, their support of Sudan which perpetrates mass killings in Darfur, and their support of Hezbollah which blows up synagogues and kills all political opponents (kills them, not arrests them), Iran cannot be considered a good guy. Second, the war of independence and Suez crisis were not of Israel's choosing. Take those first for examples. It is obviously not clear who started the 67 war, considering Egypt closed access to Israel's ports (which in International law is a deceleration of war). Whether or not you believe Israel is a legitimate country, ignoring the many threats they have faced is akin to conspiracy. Also, why do you think Israel, Europe and the gulf states would be the one's concerned with an Iranian nuclear program? Perhaps because they would be most directly affected by a bomb.
