Armando makes the important point that demands for orgasmic happy talk for any positive-sounding events tend to suppress any rational discussion of those events. This doesn't just shut down avenues of opinion, it shuts down the reporting of actual facts.
I never thought we should've invaded Iraq. But, I always wanted it to work out for the best to whatever extent that was possible. It's a shame that those who supported the war were, for the most part, more concerned with preserving the reputation of war supporters than actually doing anything to ensure that their pet project was a success. It's been a constant refrain that anti-war folks wanted things to go badly in Iraq, but it's been pro-war types who have consistently enabled the inept bungling that followed the fall of Baghdad.
