Looks like the Bush-regime will get their full-scale war, starting with an attack on Iran.
It will probably be a very strange kind of world-war I think: something like "Global Civil War" with most large cities resembling Bagdad today - including of course US cities.
After such a war, initialized by USA and Israel, there will probably be no USA and no Israel.
Remember this: Iran does actually not have any nuclear weapons, and is not an immediate threat to anyone. Developing nuclear weapons will take Iran at least 5-10 years. A nuclear Iran is NOT the real reason for that war.
The aggressor will clearly be USA & Israel.
