was/is Iraq worth it?

Beyond

the dollar cost (more debt and a further devaluation of the dollar)

and

the cost in terms of lives (American, Iraqi, and other)

and given

the unpopularity of our on-going efforts in Iraq...

was Iraq's contribution to the cost of losing Congress in 2006 (and taking what looks to be another beating in 2008) worth it?

For all of those Republicans (and the subset of those who are various forms of "conservative"), that sure seems like a high price to pay...
