"Let me give you another example. Fifty years of isolating Cuba had failed to promote democracy. It set us back in Latin America. That's why we restored diplomatic relations, opened the door to travel and commerce, positioned ourselves to improve the lives of the Cuban people. So if you want to consolidate our leadership and credibility in the hemisphere, recognize that the cold war is over. Lift the embargo. The point is, American leadership in the 21st century is not a choice between ignoring the rest of the world—except when we kill terrorists—or occupying and rebuilding whatever society is unraveling. Leadership means a wise application of military power and rallying the world behind causes that are right. It means seeing our foreign assistance as a part of our national security, not something separate, not charity."
