Are you serious? I get the feeling that most of the people who had their families killed by civil violence, or are thrown into poverty by the chaos and lawlessness that have followed the US invasion have better things to do than fill out surveys asking them if they like the USA.

Also, it seems to me your third statement is a little self-evident.

> IF things ever settle down, I guarantee you that number will go up, as people look back on the decision in hindsight, with electricity, clean water, safe streets, etc.

IF things settle down and everything works fine and dandy, of course people will agree that everything is for the best.

The problem is that things haven't settled down yet and don't look like they're going to settle down for a long while yet. Sure, big sensationalist "insurgent activity kills 500 more US troops this month" headlines have died down, but that doesn't mean the three major ethnicities of Iraq are just going to sit down at the table and try to build a better nation together while humming the captain planet theme song, especially after they've spent decades oppressing and massacring each other.
