I support it as a nation-building throwback to the Marshall Plan, but the Iraq War has morphed into a strange social experiment with occasional counter-terror ops. The US can't build nations when we're running huge deficits.
Except the Marshall Plan wasn't building nations up from scratch; it was giving money to nations who already had the human capital and simply needed money to bring they economies back. It is very rare that outside nations successfully build up human capital in an occupied territory that they are not planning on annexing.
Which is exactly why Iraq should be incorporated into the United States in some capacity.
Why? They don't want to be American and, at risk of sounding racist, we don't want them.
Hawaii didn't want to be incorporated into the United States either, but it all worked out for the best.
Iraqi oil deposits should be reason enough...
