The last paragraph of the link given is also worth reading:

Some Democrats call Republicans who make these arguments unpatriotic. Republicans reply that they're serving their country by debunking and thwarting a bad policy administered by a bad president. You can be sure of only two things: Each party is arguing exactly the opposite of what it argued the last time a Republican president led the nation into war, and exactly the opposite of what it will argue next time.

Pretty much nails it right on the head.

Unpatriotic? Really? From Democrats? Well gosh...what a thing for a Democrat to say.

If one grants that Republican opposition to Clinton's war was more political than principled, it gets pretty damn hard not to place the current antiwar movement into exactly the same category (more anti-Bush than anti-war), as opposed to the mantle of high-minded principles that it keeps trying to adopt.

The near dead silence of the current antiwar mobs during Clinton's military escapades pretty much says it all.
