Maybe they cant prove it, but when has that stopped Bush from acting without the facts first? Plus, what we DO know is that Iran has had missiles show up in Israel after they have attacked them. With Israel being the only ally we have over there in that region, is Bush going to let that go by since he wants Iran to concede that they have involvement? AND the Saudis are not really an ally, they have gone along with us just to appease us, so we wont turn on them! They would just as soon us not be over there either! Iran is behind some of the Iraqi materials and explosives and thus the Russians that supply Iran with missiles are there too. So knowing that, why are we still trying to help Russia with food for trade? We should leave their country to them completely. They are sitting back and laughing because the US has been so gullible as to think that the Russians have quit their plans against us. They dont do it face up front but they are behind in the background. Otherwise, Iran wouldnt have material from Russia that has shown that they came from there.
