The Bush administration fired Richard Clarke, first hired by Reagan, who lead the administration's policy against terrorism, and was the main agent in the Bush government concerned with Al Qaeda prior to 9/11.
Richard Clarke begged the administration to take Bin Laden seriously before 9/11. Clarke was fired because he was concerned more about Bin Laden than Hussein, who had nothing to do with 9/11.
The Bush administration punished people who didn't support their invasion of Iraq or who shifted the focus away from Iraq in favor of Al Qaeda. But this isn't only a problem for Bush's legacy. The Iraq invasion was made official US Policy in the late 90s when Chaney, Bolton, and Wolfowitz convinced
Clinton that Hussein no longer served US interests in the region. Clinton made regime change in Iraq an official policy, but it was Bush/Chaney who, as we know, found a way to give the American people the political will to invade Iraq.
9/11 was, tragically, a gift to the Bush administration. It gave them exactly what they most wanted - Iraq.
How can anyone defend Bush, who was told in August of 2001 that an attack using hijacked airplanes was imminent. Bush was advised to have planes "scramble ready" - yet, somehow, he failed to take the most basic defense protocols to defend the eastern seaboard. One of the 9/11 terrorists was being tracked in the US
prior to 9/11 by the CIA - yet this intelligence was ignored by the Bush team because they were obsessed with Hussein from day one. Bush simply had no interest in any terrorist threat that didn't serve his Iraqi agenda. The nation paid a terrible price for his neglect.
But it gets worse: the current instability in the middle east provides a further justification for the US to keep going back to the region and building bigger military bases near the world's most vital resource. Worse still: the more we build bases, the more likely there will be terrorist blowback, which blowback will provide even further justification for US intervention, which is what the neocons want. It's a tragic and self-reinforcing cycle.
Alas, the situation is much worse than anyone could ever have imagined. Think about it. We now have a major political political party who benefits
politically from a domestic terrorist attack. An attack will not only allow Republicans to win elections based on their strongest issue, national security, but it allows them to complete their foreign policy objectives in the Middle East. This fact is not only insane, it's insanely scary.
Regarding George Tenet. He was clearly a "company man" who told his boss exactly what he wanted to hear. Wow. How surprising.
The OP is probably a young kid who gets all his information from Republican sources. He is advised to read this policy paper (link below). It was presented to Clinton in the 90s by the very people who would later take over Bush's defense department. The plan to invade Iraq was an obsession of the Bush defense team well before Bush took office. The OP means well, but he would do well to consider more evidence before he asks other people to take him seriously.
