Even if we say he might have been an islamo fascist (which I think if he had a muslim name it would have come out by now), you still can’t get beyond the second point. The whole idea of terrorism is to let the world know why you’re doing what you’re doing, i.e. no yelling of Allah Akbar and no group taking credit for planning and doing the attack, no video has turned up of him in a headscarf with an AK-47 by his side filming his last words etc... If it was terrorism, we would know by now. This isn’t the Obama admin running the investigation trying to cover it up, like at Fort Hood. Even though they tried to cover it up, we still knew right away that Major Nidal did it for Islamo Fascist terrorism.
He may have been trying to take out a particular person who was opposing Islam. He obviously had a plan.
I think they should look at the Americans on board (particularly the woman who was the aviation intelligence analyst) and see if there was some kind of AQ or IS fatwa out on any of them. The copilot had trained in the US, so he might have known and hated some of these people.
Also, I think we’re going to see less and less of the Allahu Akhbar screaming, because that makes it too obvious and they’ve realized it’s bad publicity.
