In the wake of 9/11, the (real) antiwar movement was completely isolated. Trade unions and civil society organizations had swallowed the media lies and government propaganda. They had accepted a war of retribution against Afghanistan on humanitarian grounds, an impoverished country of 30 million people.
Concurrently, a fake anti-war activism emerged in the wake of 9/11 which broadly consisted in stating: "I am against the war but I support the war on terrorism". Meanwhile, several NGOs became actively involved in humanitarian projects in Afghanistan, in close liaison with USAID and the Pentagon. (See Yves Engler, The Humanitarian Invastion of Afghanistan: Occupation by NGO, Global Research, September 5, 2010).
This acceptance of the "war on terrorism" was in large part based on the acceptance of the official 9/11 narrative, namely that the US was under attack, that the 9/11 attacks were perpetrated by Muslims, that the Taliban were protecting Al Qaeda and providing refuge to its illusive leader Osama bin Laden.
Ironically, many "Progressives" in America not only accepted the official 9/11 narrative, they were also involved in smearing the 9/11 Truth Movement. By slurring those who questioned the official 9/11 story (backed by carefully researched evidence and analysis), they (unwittingly) provided legitimacy to the bombing and invasion of Afghanistan, Iraq, the Palestinian occupied territories as well as the targeting of Iran, as part of the "Global War on Terror" GWOT).
The so-called "War on Terrorism" is a lie. Amply documented, the pretext to wage this war is totally fabricated.
