The extraordinary prosperity we now enjoy we will be threatened as well as we lose our ability to persuade other nations to adopt the principles of free market so necessary to the effective functioning of a global economy. Friend and foe alike perceive a gap between a great power's rhetoric and its actions as weakness. Our enemies, of course, will soon test our resolve in other ways to determine how far they can exploit our debility. Our friends will seek new arrangements to compensate for what they perceive as our unreliability. Thus, whether we had a strategic interest in the Balkans or not we acquired one the moment we threatened force.

Second, NATO, the most successful alliance in history, would not survive another decade much less another half century should we fail to impose our will on an inferior but dangerous European power. Alliances are not ends in themselves. They are formed to protect our interests. We shouldn't neglect our interests to form alliances. For some time now, our NATO allies have been spending far too little on our mutual defense.
