Remember?

As long as we are remembering, does anyone remember how we punished Saudi Arabia who provided 18 of the 19 hijackers and much of the funding??? Why do we never discuss the root causes of the attacks? "In February 2012, former U.S. senators Bob Graham and Bob Kerrey made sworn statements filed in federal court as part of this litigation commenced by the 9/11 victims' families in which the former senators stated that the government of Saudi Arabia might have played a direct role in the 9/11 attacks. The two senators had reviewed top secret information concerning the 9/11 attacks when they were in the Senate. "I am convinced that there was a direct line between at least some of the terrorists who carried out the September 11th attacks and the government of Saudi Arabia," stated former senator Graham in his sworn court document. According to Graham's sworn statement, unanswered questions remain regarding Saudi-sponsored financial links to Al Qaeda and the role of Omar al-Bayoumi, a Saudi citizen living in San Diego with ties to two of the 9/11 hijackers and to officials of the government of Saudi Arabia.[118] There remains substantial unreleased documentation related to these issues.

On February 4, 2015, former al-Qaeda operative Zacarias Mousaoui who is imprisoned for life for his role in 9/11 attacks, told lawyers that members of the Saudi royal family, including former intelligence chief Prince Turki al-Faisal Al Saud, supported al-Qaeda to carry out its attacks.

Our purported "ally" has a lot to answer for.
