Bush in Springfield, MO

This quote from a speech delivered by Bush last week in Springfield, MO sets him apart from Kerry on terrorism and foreign policy:

See, you can't talk to the terrorists. You can't hope for the best. You can't negotiate with them. We'll engage the enemies around the world so we do not have to face them here at home. We will continue to lead the world with confidence and moral clarity. We put together a strong coalition to help us defeat the terrorists threats. Over 40 nations involved in Afghanistan. Some 30 nations are involved in Iraq. Over the next four years, I will continue to work with our friends and build alliances, but I will never turn over America's national security decisions to leaders of other countries."

I wonder where Kerry really stands on the doctrine/policy of preemption?
