Bush - Stay there indefinitely
Kerry - Stay there a few more years
Badnarik, Cobb, Peroutka, Nader- Leave as soon as is safely possible.
I believe Bush's true stance is to keep the forces there until peace has settled in and the Iraqi government asks us to leave. However, the US is petitioning to place a US base in Iraq (similar to what it did in Germany and Japan following WII) to ensure that peace remains and the Democratic process has a chance to work, as well as gives us a new launching pad in the region (now that we are leaving Saudi Arabia).
