On This Day in 9/11 History

A Timeline by William M. Arkin

 

9/11 as an event is obscure to many who didn’t live through it, little understood by those who did, controversial and impenetrable to those who think and write about it, and intentionally still hidden behind veils of secrecy, even two decades after it occurred.

To accompany the publication of History in One Act: A Novel of 9/11 (Featherproof Books), national security expert, bestselling author, and award-winning journalist William M. Arkin has compiled a year’s worth of daily insights and updates: contextual research, related historical events, and detailed background pulled from a vast trove of his career’s work. Every day, until the 20th anniversary of 9/11, there will be new information and insight posted right here.

History in One Act is a fresh retelling of the events leading up to 9/11, a novel which completely immerses readers into two worlds: one of al Qaeda, and one of American espionage. It’s a never-before-told tale of masterminds, spies, pilots, presidents, and princes—but most importantly, it tries to answer the still-unanswered question: who were the men behind 9/11?

Pakistan’s premier intelligence agency, the Inter-Services Intelligence (ISI) agency begins its own program to recruit Arab fighters from the Middle East to fight against the Soviets in Afghanistan, some two years after the invasion.

With the publication of a CIA report, “Intelligence Community Terrorist Threat Advisory”, the level of reporting on terrorist threats and planned attacks reaches its highest level since the Millennium alerts of 1999. Michael Morell, President Bush’s CIA briefer (and future acting director of the Agency) says that in the first three months of the Bush administration, there was “little to no specific threat reporting...
The CIA begins supplying select Afghan mujahidin guerrillas with shoulder-launched Stinger surface-to-air missiles to help them attack Soviet forces and shoot down helicopter gunships.

The CIA delivers two document drafts in response to National Security Advisor Condoleezza Rice’s request for a new series of authorities relating to covert action in Afghanistan and against Osama bin Laden.

Osama bin Laden begins helping Abdullah Azzam, his mentor, to run the Maktab al-Khidamat (MAK), the “Office of Services,” which becomes a key node in the private funding network for the Afghanistan war and is the “precursor organization to al Qaeda.” (9/11 Commission Report, p. 89) While living full-time in Pakistan, bin Laden also supports the building of six Arab-only training camps in Afghanistan,...
Secretary of State Madeleine Albright delivers a speech at Georgetown University in which she argues that sanctions likely will not end until Saddam is replaced. This no normalization without regime change is the policy adopted by two administrations and the roots of the second Gulf War.

Saudi King Faisal (Faisal bin Abdulaziz Al Saud) is assassinated by a member of the royal family, his killing ascribed to his program of modernization. His half-brother’s son shoots him point blank driven, the story goes, by Faisal’s support for television broadcasts. When first introduced in 1965, Faisal assuages the religious community by broadcasting prayers. But ultraconservatives still undertake violent protests. The assassin’s brother...
Osama bin Laden leaves Afghanistan for Sudan, partly because of the intractability of the Afghan domestic situation and the endless fighting amongst rival groups and partially because he is concerned for his own safety, with reports of Saudi-sponsored assassination attempts on his life being carried out by Pakistan. Bin Laden and Prince Turki, head of Saudi intelligence, supposedly have a fundamental break, bin Laden...
Mahmoud Abouhalima (Abu Halima) (“The Red”) is forcibly rendered to the United States, the first known extraordinary rendition.

Abouhalima fled to Egypt and was picked up by Egyptian...

Abdel-Rahman...
A Japanese doomsday cult organization, Aum Shinrikyo, plants sarin nerve gas in the Tokyo subway system, killing 12 and injuring some 5,700.

Hail Caesar! Bill Clinton nominates George Tenet to be the director of the CIA, and all of Washington celebrates.

The CIA produces a report on Osama bin Laden’s attempts to acquire uranium. It is based upon the interrogation of Jamal al-Fadl, a defector from bin Laden’s camp in Sudan.

Lake’s nomination came under fire from Republicans in Congress, though the specific indictment against him is that he...
Iraq uses chemical weapons against Kurdish civilians in the village of Halabja, killing perhaps thousands. Saddam Hussein had begun the "Anfal" campaign against the Kurds of northern Iraq a month before, eventually killing over 100,000 civilians and destroying over 1,200 Kurdish villages. Since the end of the monarchy in 1959, the Kurds have opposed Baghdad rule of their northeastern homeland.
The CIA briefs National Security Advisor Condoleezza Rice that its “preliminary judgment” is that a “strong circumstantial case” can be made that al Qaeda was behind the October 2000 attack on the USS Cole in Yemen, but that it lacked “conclusive information on external command and control” of the attack. A week later, Roger Cressey on the NSC staff writes to Deputy National Security...

CIA director George Tenet later writes: “These authorities would...
