If Bush is re-elected, we will never find out, at least for four more years. Cheers.
I am afraid that the expansion is bipartisan unstoppable trend, be it Yugoslavia or Iraq. Bush even tried to stop it (as he promised in his 2000 campaign) and failed. Maybe we are watching something like Greek tragedy (or maybe Spanish since it was Spain the first global superpower which could not stop until she collapsed from exhaustion).
I doubt that neocons really can control this trend, rather they are superficial intellectuals who happen to flow with the current and stay on the surface.
