The actual “front line in the war on terrorism” is at the US Consulates who either allow people visas to enter the United States, or they don’t. All 9/11 hijackers received US visas that allowed them to come into the country, although, according to Michael Springmann, the man who used to run that consulate section in Jeddah, Saudi Arabia — NONE OF THE HIJACKERS WAS “QUALIFIED” TO RECEIVE A VISA AND ENTER THE COUNTRY.
Springmann has told of his experiences in Saudi Arabia for about a decade now. He made official complaints against the CIA during his tenure for their illegal issuing of Visas to militants, connected to the ongoing “Jihad” in Afghanistan against the Soviet Union.
The United States federal government was FOR terrorism a long, long time before it was allegedly against it. See more at George Washington’s Blog.
