The $150 billion is nothing. What has really driven the decline in the value of the dollar has been the enormous cost of that idiotic nation-building project in Iraq. The cost of that thing — most of which has been financed through off-budget appropriations, mind you — makes a $300 billion highway bill look like pocket change.
Even at a trillion $ it'll be a great deal. Or would you prefer Iraq's oil money and future were devoted to supporting global terrorism or a militaristic dictator? There aren't any other choices in that region -until now.
Yes, there are terrorists and Al Queada in Iraq, just as in most Arab nations but only in Iraq do they fight for their existence and are killed on a daily basis.
