Bush has begun talking Armageddon again. Stating that Iran will cause him to set off World War III. This nut wants to hold us all hostage... telling the World that if another sovereign Nation does not do exactly what he says, he is willing to start a 3rd World War. In essence...he wants to hold us at gun point.
And of course the rest of the Country is sleeping on his comments (too busy watching football and driving their SUV's...of which they won't be able to gas up pretty soon because prices will be too damn high. But until then... people will remain in La La Land). Even during the Cold War, American Presidents generally refrained from such talk.
Bush's comments were in direct response to Vladimir Putins warning to the U.S., not to attack Iran. The message was intended for Russian ears, just as much as it was intended for Iran. Of course any war with Iran risks drawing in Russia, Israel and other countries in the region.
