Of course there was homeland security. Billions of dollars is spent on the military and supposedly the Pentagon was the most protected building in the world. I don't even think I can sit on the fence on this. Half of the so called hijackers were alive and well after the event. There was no evidence of a pasenger plane hitting the Pentagon. The third tower collapsed exactly like a controlled demolition. The phone calls to loved ones were impossible. Looking at how US elites act around the world, it is no surprise that they would kill their own in an attempt to control yet more regions.
