We all remember that the GOP called Kerry at their convention. But, Let's take a look at the record:

Bush then:

I think we've got to be very careful when we commit our troops. The vice president and I have a disagreement about the use of troops. He believes in nation building. I would be very careful about using our troops as nation builders. I believe the role of the military is to fight and win war and therefore prevent war from happening in the first place. So I would take my responsibility seriously.
--George W. Bush, First Gore-Bush debate, October 3, 2000
Bush now:

A broad Pentagon directive issued this week orders the U.S. military to be sure, the next time it goes to war, to prepare more thoroughly for picking up the pieces afterward.
More than a year in the making, the directive represents an ambitious attempt to bring about a fundamental, permanent widening in what U.S. troops are trained and equipped to do. Accustomed to focusing primarily on combat operations, U.S. forces under the new order must now give post-conflict stability operations similar priority, which means they must be ready in foreign countries to carry out such tasks as developing political institutions, establishing judicial systems and reviving economic activities.
