"[According to Al Qaeda's spokesperson Abu Suhail] Late al-Qaida leader Osama bin Laden in his many audio and video messages praised the attacks several times and in 2004 he publicly acknowledged al-Qaida’s involvement....For Iran, anti-Americanism is merely a game of politics. It is anti-American when it suits it and it is a collaborator with the U.S. when it suits it," (Inspire Magazine, September 2011)
The "Global War on Terrorism" propaganda stint leaked through the CIA's Al Qaeda operative in the Arabian Peninsula (AQAP) has visibly backfired.

From the Horse's Mouth: Al Qaeda candidly acknowledges its role in the 9/11 attacks, while at the same time denying Iran's involevement as a "state sponsor" of terrorism.
In a twistedirony, these scripted Al Qaeda accusations have put to rest Washington's allegations that Iran supported Al Qaeda and was complicit in the 9/11 attacks.
Moreover, if Al Qaeda and Iran are longer friends, the Tehran government can no longer be upheld as "a state sponsor of terrorism". This in itself drives a wedge into the National Security Strategy, thecornerstone of which is based on "state sponsorship of terrorism" as a justification  for waging the "Global War on Terrorism" (GWOT). 
Theater of the absurd: If the Islamic Republic of Iran is an enemy of Al Qaeda, pari passu the justification for waging a pre-emptive war on Iran falls flat, the "Global War on Terrorism" collapses like a deck of cards.
