The United States has covered up the “major role” of Saudi Arabia in planning the September 11, 2001 attacks which killed nearly 3,000 people, an analyst said. “The dust has not entirely settled over the causes of 9/11 but the heavy hand of our good friends, the Saudis, played a major role in that and it was covered up from the get-go,” Bill Jones, the Washington bureau chief for Executive Intelligence Review, said on Thursday. He added that the US intelligence services may have been involved in the attacks "through their relations with the Saudis." A federal appeals court in New York City has revived litigation against Saudi Arabia on behalf of families of victims of the 9/11 attacks. More than eight years after a lower federal court ruled Saudi Arabia had immunity from prosecution, a three-judge panel of the 2nd US Circuit Court of Appeals in Manhattan ruled on Thursday that families of 9/11 victims can get their day in court against Saudi Arabia. According to the families of the victims, the kingdom had provided support to al-Qaeda prior to the attacks. The United States instead launched an offensive against Afghanistan in the wake of the 9/11 attacks “because they felt someone must respond,” Jones noted. More than 12 years after the invasion, the analyst said, there is growing anger among Americans over the war as it is wasting “treasure and blood” and achieving “nothing” for their country. “People really feel that we have done a lot and it has led to nothing essential in terms of defense of the United States,” he said. “So the anger is building more and more.” According to an Associated Press-GfK poll released on Wednesday, a majority of Americans believe the war in Afghanistan was the “wrong thing to do” and want President Barack Obama to pull US troops out of the country faster than he is doing. The poll found that 57 percent of Americans say going to war in Afghanistan was the “wrong thing to do” and 53 percent say the speed of the planned withdrawal from the Asian country is too slow. Just 16 percent of those surveyed said they expected the situation in Afghanistan to “get better” over the next year if US troops remain while 32 percent said they expected it to “get worse.” About half said they expected the situation to “stay about the same.”
