Mark Steyn discusses Saddam Hussein's disappearing WMD, and makes a stunning observation:

The Left is remarkably nonchalant about these new terrors. When nuclear weapons were an elite club of five relatively sane world powers, the Left was convinced the planet was about to go ka-boom any minute, and the handful of us who survived would be walking in a nuclear winter wonderland. Now anyone with a few thousand bucks and an unlisted number in Islamabad in his Rolodex can get a nuke, and the Left couldn't care less.

Conservatives shouldn't assist the Western world's self-loathing fringe in imposing a burden of proof that can never be met. The alternative to pre-emption is defeat. If you want a real "underlying issue", that's it.
