Slate's Christopher Hitchens

".....So Saddam Hussein finally got his reward for all the unpunished times.
Well, history doesn't move in a straight line, and irony is a dialectical
hairpin. But if he really didn't have any stores of unlawful WMD, it was
very dumb of him to act as if he still did or perhaps even to believe that
he still did. And it seems perfectly idiotic of anybody to complain that we
have now found this out (always assuming that we have, and that there's no
more disclosure to come). This highly pertinent and useful discovery could
only be made by way of regime change. And the knowledge that Iraq can be
finally and fully certified as disarmed, and that it won't be able to rearm
under a Caligula regime, is surely a piece of knowledge worth having in its
own right and for its own sake."

Christopher Hitchens Slate, 2004

20 years ago he was a Stalinist.
Now he's a Republican.
20 years from now . . who knows?
