Some of the articles claiming the US political right is involved are relatively speculative and hysterical. The US right might be involved. Flip a coin. I've seen a lot of bad reporting. There is a current faction fight inside the government between the people who want to stomp Arabs and Muslims and the people who want to stomp US right-wing groups. It is a civil lberties nightmare.
Let's be cautious in the blame game.
