Why can't Bush admit to defeat?

As the U.S. Government marks the four year anniversary since the start of the Iraq war it really makes you wonder how many more people have to die before Bush will get it through his thick skull that the war is a failure. Since March 19, 2003 approx 3021 U.S. military men and women and ten of thousands of Iraq civilians have died, yet Bush continues to ask the American people for more time.
According to the L.A. times more then 59% of the American people want the U.S. out of Iraq and they want it now. Yet Bush continues to make statements such as "It can be tempting to look at the challenges in Iraq and conclude our best option is to pack up and go home, that may be satisfying in the short run, but I believe the consequences for America's security would be devastating." He then goes on to try and use the fear tactic stating that if American troops where to pull out now and leave Iraq in the state that it is in now, that it would create a new breeding ground for terrorists that once felt that they had a save haven in Afghanistan to move into Iraq. He then goes on to say "the same terrorists that were responsible for the attacks of 9/11". Well when I read this a few things just happened to come to mind.
For one thing if the Bush administration would have focused their time and energy going after those responsible for 9/11 following the attacks, then maybe just maybe the government wouldn't have to spend billions of dollars in trying to prevent the "terrorists" from moving into Iraq. Second why the hell did the U.S. invade Iraq in the first place? The Bush administration still has not given anyone a straight answer when it comes to that question. Thirdly I honestly do not think that the U.S. leaving Iraq now or another 4 years from now is going to make any difference in the way the "terrorists" feel about the American government. If anything them invading Iraq just made things worse for them in my eyes, they have just given the "terrorists" more of a reason to hate them.
The sad thing about all of this is that Bush used and continues to use the deaths of thousands of innocent people on 9/11 as an excuse, as a reason to go ahead of continue to murder thousands of other innocent people in Iraq. In the end no one is going to come out of this as victorious, no matter what the Bush administration says or how hard they try. The simple fact is they went into this war based on lies, lies that the American people felt they had to buy. Lies that the American people were told in a time when they were most vulnerable, in a time when all they could think about was making someone pay for what was done to them, and can you blame them? No, not really.
What it comes down to is that the U.S. needs to pull out, they need to stop shoving democracy down every ones throats.......democracy does not work for everyone. So Bush needs to suck it up and realize he has LOST! He has lost the war in Iraq and for the most part he has lost the trust of the American people. So go ahead and tell yourself that you are doing the right thing Bush, it seems to help you sleep at night, but keep in mind no one is buying your shit anymore.
