American intervention has broken pottery all over the Middle East. Every time the U.S. attempts to repair its last accident, it increases and spreads the mess. It is time for a different approach. One in which Washington does not attempt to micromanage the affairs of other nations. In which Washington practices humility. This would not be isolationism. America, and especially Americans, should be engaged in the world. Economic and cultural ties benefit all. Political cooperation can help meet global problems. Humanitarian needs are varied and manifold. Military action sometimes is necessary, but only rarely -- certainly far less often than presumed by Washington.
