Here is a benchmark after a day of polling:

2 say "Yes, the war it was worth it" (15.38%)
11 say "No, the war was not worth it" (84.62%)

With this very small sample of canncom respondents, the results show less support than a CBS poll found among Americans in general: Poll: Most Americans Say War Not Worth It, 64 Percent Say Results Of War Not Worth American Lives Lost - CBS News

According to that CBS poll, 29% think it was worth it, and 64% think not. This is actually up form March 2006, when only one in four Americans said the war was worth the costs --- that was surprising to me.

Anyway, I hope a few more canncom members chime in on this important question.
