The Iranian bomb program is apparent to all except those who chose to bury their heads for ideological reasons. It's beyond speculation at this point and will result in a massive regional nuclear arms race. Israel never threatened to nuke anyone. It's threats are to bomb the secret factories to prevent a future catastrophe. Who believes North Korea would be shelling the south with impugnity if it hadn't first gotten the bomb? The Iranian bomb is not about establishing "parity" or a balance of power. It's about spreading their messianic expansionist dream under cover of nukes. Wikileaks shows Iran's program is freaking everyone out, not just Israel.
