Nothing. The hard part is that one of them left behind a Rosetta Stone so that the FBI gave the US Congress full license to greenlight non-stop military invasions in the Middle East. Apparently there was enough in that bag to convince the world that there was an international terrorist conspiracy and that its primary goal was to destroy American Freedom. And it was being run out of AfghanistanIraqIran.
Actually I would say that the WTC attacks gave a "full license to greenlight non-stop military invasions in the Middle East." Compared to the WTC attacks the Pentagon attack would have been pointless. It makes no sense to commit the Pentagon attack after you have successfully committed the WTC attacks unless you are stating that the US government just happened to plan the Pentagon attack on the same day Osama planned the WTC attacks?
And the US didn't have problems invading countries before the 9/11 attacks so the idea that the 9/11 attacks were a casus belli is just giving American propagandists more credit then they deserve.
The images of the plane hit on the Pentagon, like the one you linked, just never show a plane. I have seen downed planes before, and they pretty much always leave debris. I know these things are full of gas, but just how hot does it burn? Can it evaporate an entire plane and leave the cars nearby just a little scorched?
I am not saying that no plane hit the Pentagon. Something did, maybe a plane. But the photos just never show it. Too much is classified. It's really odd.
Anyway, that's one great building. Huge. Folks working on the other side of it didn't even know it had been hit. It was on fire for two days with people working in it. If I had to work in a building that was gonna be attacked by terrorists, I'd pick the Pentagon. That or the UN General Assembly. It'd be cool to work in New York.
Well perhaps there are no pictures of the plane crashing into the Pentagon because unlike the WTC, there aren't hundreds of people with cameras walking around. We are talking about a top secret area of the US that was hit.
"I felt insulted until I realized that the people trying to mock me were the same intellectual titans who claimed that people would be thrown out of skyscrapers and feudalism would be re-institutionalized if service cartels don't keep getting political favors and regulations are cut down to only a few thousand pages worth, that being able to take a walk in the park is worth driving your nation's economy into the ground, that sexual orientation is a choice that can be changed at a whim, that problems caused by having institutions can be solved by introducing more institutions or strengthening the existing ones that are causing the problems, and many more profound pearls of wisdom. I no longer feel insulted because I now feel grateful for being alive and witnessing such deep conclusions from my fellows."
