I hope this isn't a dupe, but I searched here and couldn't find:
The Pentagon's "Second 911"
"Another (9/11) attack could create both a justification and an opportunity to retaliate against some known targets"
by Michel Chossudovsky
August 10, 2006
One essential feature of "defense" in the case of a second major attack on America, is "offense", according to Homeland Security Secretary Michael Chertoff: "Homeland security is one piece of a broader strategy
brings the battle to the enemy."(DHS, Transcript of complete March 2005 speech of Secr. Michael Chertoff)
In the month following last year's 7/7 London bombings, Vice President Dick Cheney is reported to have instructed USSTRATCOM to draw up a contingency plan "to be employed in response to another 9/11-type terrorist attack on the United States". Implied in the contingency plan is the certainty that Iran would be behind a Second 9/11.
This "contingency plan" uses the pretext of a "Second 9/11", which has not yet happened, to prepare for a major military operation against Iran, while pressure was also exerted on Tehran in relation to its (non-existent) nuclear weapons program.
What is diabolical in this decision of the US Vice President is that the justification presented by Cheney to wage war on Iran rests on Iran's involvement in a hypothetical terrorist attack on America, which has not yet occurred:
The plan includes a large-scale air assault on Iran employing both conventional and tactical nuclear weapons. Within Iran there are more than 450 major strategic targets, including numerous suspected nuclear-weapons-program development sites. Many of the targets are hardened or are deep underground and could not be taken out by conventional weapons, hence the nuclear option. As in the case of Iraq, the response is not conditional on Iran actually being involved in the act of terrorism directed against the United States. Several senior Air Force officers involved in the planning are reportedly appalled at the implications of what they are doing—that Iran is being set up for an unprovoked nuclear attack—but no one is prepared to damage his career by posing any objections.
