The US and its sidekick the UK have messed up Iraq. Saddam was clearly an awful thug, and he and his henchmen perpetrated war crimes such as genocide against elements of the population.
Despite that, for the majority of people living there, life was a reasonably secure one, in which clans kept social order, and where there were highly developed educational and professional streams. There was almost no sectarian violence, Christians lived freely, urban women did not wear the hijab, could drive, and life could go on.
It's hard to imagine the most pro-American/pro-British Iraqi thinking that things have got better
in any way since the invasion. Indeed, one proposal tossed around the US media is to try to find strongman (like Assad, Saddam, or Mubarak) to get the country under control.
Either the US and UK need to get out now, admit their screw up, and stand by guiltily as the Iraqis forge some sort of order. Chaos never goes on for ever. I suspect that the main reason for not doing this is that Iran will emerge as a greater regional power.
Or perhaps the US and UK need to go to war. I mean really go to war to win, and commit enough forces to suppress insurgents.
Without Bush's (or more probably Rumsfeld and Cheney's) messed up initial war, the situation would be so much better now. They could have followed Colin Powell and sent 500,000 troops in.
And the US had the troops: it just did not use them.
The United States Army as of 2004, consisted of 494,295 soldiers on active duty, 342,918 in the Army National Guard (ARNG) and 204,134 in the United States Army Reserve (USAR). [Wikipedia]
The Marines as of 2005 had 180,000 active duty and 40,000 reserves. [Wikipedia]
The U.S. Navy currently numbers nearly 500,000 men and women on active duty or in the Navy Reserve and operates 282 ships and more than 4,000 aircraft. [Wikipedia]
The Airforce has 352,000 men and women on duty. [Wikipedia]
Altogether that is 2,113,000 active and reserve duty military. Perhaps another half million were available in potential coalition partners.
A real war, using the power available has not been fought, and it is a prime duty of those who engage in war to commit to winning it. In this above all, the "easy" air-strike wars of the 1990s lead to a massive misjudgement by the US leadership. It is this leadership which thus bears the direct responsibility for Iraq.
The choice now is not to "stay the course", but to either fight the war with the resources necessary to win, or quit.
The big problem with all this is that it may be too late. If it is too late, there is only one logical conclusion. Withdraw. Admit yet another American defeat.
And then settle down to dealing with Iran.
