Six years after 9/11, the American public have still not been provided with a full and truthful account of the single greatest terror attack in US history.

What they got was a turkey. The 9/11 Commission was hamstrung by official obstruction. It never managed to ascertain the whole truth of what happened on September 11 2001.

Six years after the 9/11 terrorist attacks, the entity known as al-Qaeda remains largely a mystery: its intent, its ideology, its leadership, and its inner workings are all largely unknown to the American people. Experts study them and interpret the arcane meanings of their utterances in light of Koranic verses. The president of the United States and his allies aver that they hate us because we’re so free, so prosperous, so utterly fabulous – yet still al-Qaeda is, at least in the popular mind, an army of shadows, in the sense that they don’t seem quite real.

Airlines sued by victims of the September 11 attacks filed complaints with a U.S. court on Tuesday to compel testimony from FBI and CIA agents in a bid to make the federal government more culpable for not preventing the attacks.

In separate complaints filed in the U.S. Court for the Southern District of New York, seven U.S. airlines sought testimony from two members of a U.S. Central Intelligence Agency unit that investigated Osama Bin Laden and five current and former FBI agents who investigated al Qaeda.

Fidel Castro suggested that Washington has deliberately failed to stop terrorist attacks against Americans because it needed to “deliver a bang” that would justify its war on terror.

In the latest in a series of essays that Cuba’s 80-year-old Maximum leader has begun writing every few days, Castro on Sunday seized on U.S. Homeland Security Secretary Michael Chertoff’s comments this past week expressing a “gut feeling” that the United States faces an increased risk of attack this summer.

“The government of the United States sees and hears all, with or without legal authority,” Castro wrote. “They can prevent any attack on their people, unless there is some imperial need to deliver a bang so that they can carry on with and justify the brutal war which has been declared against the culture, religion, economy and independence of other peoples.”

Al-Qaida is using its growing strength in Pakistan and Iraq to plot attacks on U.S. soil, heightening the terror threat facing the United States over the next few years, intelligence agencies concluded in a report unveiled Tuesday.

At the same time, the intelligence analysts worry that international cooperation against terrorism will be hard to sustain as memories of Sept. 11 fade and nations’ views diverge on what the real threat is.
