Vronsky, I think you should factor into your psychological profiling of me that I have no qualms about members of US government plotting to kill US citizens to make a case for war. Members of US government are more than happy to kill US American citizens through police violence, poverty, monetary bars to healthcare, sending them to fight in the Middle East, pollution, and a host of other methods, so I don’t see why warmongering should be any different.
Quite apart from consideration of the physics (which itself is unambiguous), I severely doubt pre-rigged explosives because it would have been far too fucking easy to get caught.
