Oops, how quickly one remembers. Let’s preempt our under-loved neighborhood 711 pipe plumbing driller from chiming in with contradictory research skills boasting on the subject by clarifying Pakistan’s role in 9/11 conspiracy [strike]fact[/strike] allegation… (if ‘fact’ is something to be “proven”)
A senior-level U.S. government source told CNN in October of 2001 that U.S. investigators believed Ahmed Omar Saeed Sheikh (Ahmed Umar Syed Sheikh), a long time ISI asset, using the alias Mustafa Muhammad Ahmad, sent more than $100,000 from Pakistan to Mohammed Atta, the suspected hijack ringleader of the September 11, 2001 attacks.
“[color=#0040BF]Investigators said Atta then distributed the funds to conspirators in Florida in the weeks before the deadliest acts of terrorism on U.S. soil that destroyed the World Trade Center, heavily damaged the Pentagon and left thousands dead…
Syed also is described as a key figure in the funding operation of Al-Qaeda, the network headed by suspected terrorist mastermind Osama bin Laden.”
The Pittsburgh Tribune notes “[color=#0040BF]There are many in Musharraf’s government who believe that Saeed Sheikh’s power comes not from the ISI, but from his connections with our own CIA.[/color]”
CNN later confirmed that it was “[color=#0040BF]Ahmed Umar Syed Sheikh, whom authorities say used a pseudonym to wire $100,000 to suspected hijacker Mohammad Atta, who then distributed the money in the United States.[/color]”
Soon after the money transfer was discovered, the head of Pakistan’s Inter-Services Intelligence, Gen. Mahmood (Mahmud) Ahmed, resigned from his position. Indian news outlets reported the FBI was investigating the possiblity that Gen. Mahmood Ahmed ordered Saeed Sheikh to send the $100,000 to Atta, while most Western media outlets only reported his connections to the Taliban as the reason for his departure from the ISI. 
The Wall Street Journal was one of the few Western news organizations to follow up on the story, citing the Times of India: “[color=#0040BF]US authorities sought [Gen. Mahmud Ahmed’s] removal after confirming the fact that $100,000 [was] wired to WTC hijacker Mohammed Atta from Pakistan by Ahmad Umar Sheikh at the instance of Gen Mahumd.[/color]” The best coverage came from The Daily Excelsior, reporting “[color=#0040BF]The FBI’s examination of the hard disk of the cellphone company Omar Sheikh had subscribed to led to the discovery of the “link” between him and the deposed chief of the Pakistani ISI, Gen. Mehmood Ahmed. And as the FBI investigators delved deep, sensational information surfaced with regard to the transfer of 100,000 dollars to Mohammed Atta, one of the Kamikaze pilots who flew his Boeing into the World Trade Centre. Gen. Mehmood Ahmed, the FBI investigators found, fully knew about the transfer of money to Atta.[/color]”

In case a challenge presents itself against Pakistan’s connection with the alleged conspirator OBL/UBL, bets are in favor of name calling over actual research or logic. Any takers?
