My first duty as Commander-in-Chief is to defend the United States of America. In doing so, the question is not whether America leads in the world, but how. When we make rash decisions, reacting to the headlines instead of using our heads; when the first response to a challenge is to send in our military -- then we risk getting drawn into unnecessary conflicts, and neglect the broader strategy we need for a safer, more prosperous world. That's what our enemies want us to do.
