The national security act of 1947 (I think) was the start of it introducing acts that go against the people's liberties. And later on, under Bush Junior's administration the patriot act was implemented. And then after 9/11 the National Defense Authorization Act was implemented, robbing the people of their liberty by giving the state the power to indefinitely detain american citizens if only they were SUSPICIOUS of them. Without trial and legal representation at all.Because of balancing the profit vs gain .... Inside jobs are usually done when the gain is much much more than the loss, and causing an event that would would cause a great economic loss for going to a war which IS a great economic burden is stupid while you can blow up lesser buildings and earn the same result through the press.
U.s.a. has a ''defence'' department. Under their old ''war'' department they only fought 3 wars. The spanish american war, ww1 and ww2. Under the ''defence'' department where they were only ''defending'' themselves, they fought dozens of wars. It's a public relations move. Just like the modern day ''homeland security''.
You should reconsider the ''gains''. Why would our owners care about the financial damage 9/11 brought if they own 97% of all the wealth on earth. There were plenty of political, socialist gains after 9/11.
