Bush is a bully and a coward at heart. Iraq was chosen because Iraq would be easy, and then the rest of the Middle East would follow. It was the easy way to solve our problems, not our real problems, but our emotional pain, the unresolved conflict over being attacked. And Bush would resolve his lifelong lack of success.
Bush will not leave Iraq, not because he thinks we can win, or he thinks it's part of the war on terror. But because he cannot face another failure. Which is why Scowcroft and Baker have had no influence on him. They are his father's men, veterans, despite their politics, realists. Bush is not and never has been. When he wasn't hiding from his failure with booze and coke, he hid from it with Jesus. Now he has Henry Kissinger whispering in his ear, telling him what he wants to hear. He doesn't want advice, he wants support and only support. Those who do not support him, are diminished, then banished.
This is a man who has never honestly looked himself in the face and said I have failed. He has always been protected from failure.
Read it all, you'll be glad you did.
