Regarding the "estimated" strength of Al Quaeda: It's hard to find a current (within last 6 months) legitimate estimate. What I found was:
"At the center of the debate are the counter-terrorist community's two leading scholars, Marc Sageman and Bruce Hoffman. A former CIA officer and forensic psychiatrist, Sageman argues in his new book Leaderless Jihad that Al Qaeda's core operational capabilities are no more. What remains is a ragtag cohort of self-radicalized "wannabes" throughout the West and the greater Muslim world, unpredictable and dangerous but largely incapable of carrying out major attacks."
Bruce Hoffman, professor at Georgetown University's School of Foreign Service, strongly criticized Sageman's Leaderless Jihad: Terror Networks in the Twenty-First Century. Hoffman, using a report compiled last February by Mike McConnell the Director of the National Intelligence Agency, contends:
"al Qaeda is alive and well and plotting high-profile terrorist attacks much as it did before 9/11. Al Qaeda and its terrorist affiliates continue to pose significant threats to the United States at home and abroad, and al Qaeda's central leadership based in the border area of Pakistan is its most dangerous component. al Qaeda continues to exercise top-down direction and guidance even though it "has lost many of its senior operational planners over the years. . . . The group's adaptable decisionmaking process and bench of skilled operatives have enabled it to identify effective replacements." Members of al Qaeda in Iraq have been dispatched "to establish cells in other countries" casts further doubt on Sageman's claims regarding al Qaeda's bottom-up organizational structure."
Soooo, I'd have to say the jury is still out on the actual strength of Al Quaeda, in Pakistan or anywhere else.
In addition, I don't buy equating military deaths in Iraq or Afghanistan to deaths resulting from attacks on our homeland. Dead is dead, but they are not equivelant in their nature.
It's all too common and convenient to forget that, at the time we entered the Iraq war, the vast majority of the Congress and Senate (including what I now call hypocritical Democrats) backed Bush based on their assessment of the potential danger to us at the time.
My main contention, that an unbiased history will look at Bush a lot different than you and Chosen do is still valid. It will be much like what has happened to Truman's reputation. If you continue to live the profligate life style of an academic you probably won't be around to see it.
