Report of the 9/11 Commission

SPECIFIC FINDINGS
Unsuccessful Diplomacy
Beginning in February 1997, and through September 11, 2001, the U.S. government tried to use diplomatic pressure to persuade the Taliban regime in Afghanistan to stop being a sanctuary for al Qaeda, and to expel Bin Ladin to a country where he could face justice. These efforts included warnings and sanctions, but they all failed.

The U.S. government also pressed two successive Pakistani governments to demand that the Taliban cease providing a sanctuary for Bin Ladin and his organization and, failing that, to cut off their support for the Taliban. Before 9/11, the United States could not find a mix of incentives and pressure that would persuade Pakistan to reconsider its fundamental relationship with the Taliban.

From 1999 through early 2001, the United States pressed the United Arab Emirates, one of the Taliban's only travel and financial outlets to the outside world, to break off ties and enforce sanctions, especially those related to air travel to Afghanistan. These efforts achieved little before 9/11.

Saudi Arabia has been a problematic ally in combating Islamic extremism. Before 9/11, the Saudi and U.S. governments did not fully share intelligence information or develop an adequate joint effort to track and disrupt the finances of the al Qaeda organization. On the other hand, government officials of Saudi Arabia at the highest levels worked closely with top U.S. officials in major initiatives to solve the Bin Ladin problem with diplomacy.
