How did this issue become so oversimplified? There are complex reasons for each nation to defend its interests in Iraq.
If, CKB, you believe the party line that the US' only interest was to liberate the Iraqi people, then you have more research to do.
I, for one, refuse to make this an issue of absolutes. Each nation acts in its own self-interest based on many factors including: politics, economics, and history.
