I'll meet you half way and say the government is ultimately responsible for 9/11. Decades of playing in the sandbox stirred up a mess. Fine.

But let's pretend I was totally on board with it being an inside job, this is a terrible argument.

Assume for a moment that Saudi terrorists are flying a plane at the Pentagon. Would they just roll along the ground, or would they try to come in at an angle? Also, stab in the dark, they probably meant to hit the center of the complex, not just one wall. (It was the first time they had done this, after all😛)
