Bush is going to get us in a war in 2012...thats my guess
He'll be out of office by next February. If by some strange coincidence, Bush actually does get re-elected, his presidency would end in 2008 anyway. No president can be elected for more than two terms.
Anyway, while we brought freedom from the Taliban to Afghanistan, most of people in the country are still living under the same oppressive warlords they always have been. Freedom... yeah. As for Iraq, Saddam may have been a dictator who gassed his own citizens, but he kept the country under control. The new Iraqi government has no control. If we left the country right now, there would be a massive power vacuum.
