VIRGINIA POSTREL WRITES:

The danger may make international support more valuable. But that support does not significantly reduce the risks of war. The only reason to go to war, taking enormous risks today, is to prevent greater risks tomorrow. Wisdom dictates that we make that decision based on the worst-case assumptions about war today, not on happy scenarios of easy victory with minimal casualties. That’s true with or without international support. And it was true before Powell’s speech.

Indeed.
