Like others have said, don't play poker with him if you think he is clueless.
Clinton engaged in "nation building" in Haiti. Haiti is on the verge of a revolution. So much for Clinton's "nation building.". There is no guarantee that President Bush will be successful in installing permanently friendly governments in Afghanistan and Iraq. The alternative is to cut and run like the Democrats want him to, and guarantee future disasters. In time the Democrats will probably get their wish. We will retreat to our borders and wait for the final battle. Of course one thing is certain. If Democrats are in power, and that power is threatened, they will use all manner of weapons, nuclear, biological and chemical, and break all manner of international agreements and protocols - to keep that power.
It only guarantees future disasters if we do nothing. We are certainly better off without the Taliban, and without Hussein. Even if both regimes returned they would be many years behind where they were two years ago. If they, or their replacements, were to make threatening military progress we could always return to do what we have already done.
I certainly don't advocate waiting, but I do not think we have any obligation to help them rebuild either.
