Especially in light of the refusal to release the JFK assassination files, it's mind-boggling that they've finally released this information. Seven different times, Bush was informed of imminent strikes by Bin Laden, and he simply ignored them? I guess they were so determined to go to war, they wanted any excuse they could get:

Over 120 CIA documents concerning 9/11, Osama bin Laden and counterterrorism were published today for the first time, having been newly declassified and released to the National Security Archive. The documents were released after the NSA pored through the footnotes of the 9/11 Commission and sent Freedom of Information Act requests.

The material contains much new information about the hunt before and after 9/11 for bin Laden, the development of the drone campaign in AfPak, and al-Qaida’s relationship with America’s ally, Pakistan. Perhaps most damning are the documents showing that the CIA had bin Laden in its cross hairs a full year before 9/11 — but didn’t get the funding from the Bush administration White House to take him out or even continue monitoring him. The CIA materials directly contradict the many claims of Bush officials that it was aggressively pursuing al-Qaida prior to 9/11, and that nobody could have predicted the attacks. “I don’t think the Bush administration would want to see these released, because they paint a picture of the CIA knowing something would happen before 9/11, but they didn’t get the institutional support they needed,” says Barbara Elias-Sanborn, the NSA fellow who edited the materials.

[...] Many of the documents publicize for the first time what was first made clear in the 9/11 Commission: The White House received a truly remarkable amount of warnings that al-Qaida was trying to attack the United States. From June to September 2011, a full seven CIA Senior Intelligence Briefs detailed that attacks were imminent, an incredible amount of information from one intelligence agency. One from June called “Bin-Ladin and Associates Making Near-Term Threats” writes that “(redacted) expects Usama Bin Laden to launch multiple attacks over the coming days.” The famous August brief called “Bin Ladin Determined to Strike the US” is included. “Al-Qai’da members, including some US citizens, have resided in or travelled to the US for years, and the group apparently maintains a support structure here,” it says. During the entire month of August, President Bush was on vacation at his ranch in Texas — which tied with one of Richard Nixon’s as the longest vacation ever taken by a president. CIA Director George Tenet has said he didn’t speak to Bush once that month, describing the president as being “on leave.” Bush did not hold a Principals’ meeting on terrorism until September 4, 2001, having downgraded the meetings to a deputies’ meeting, which then-counterterrorism czar Richard Clarke has repeatedly said slowed down anti-Bin Laden efforts “enormously, by months.”
