Jignat;
I've read just about everything Pinker writes. I am habitually pessimistic. Your comment is obviously optimistic to you. You make a vague estimate of the possibility of overt war between the USA and Russia. Saying the possibility is "remote" lacks a numerical estimate of its probability. Even if the probability of it was .001 I would consider that intolerable when considering the consequences. Remember the USA felt the Japan situation in 1945 was serious enough to use nuclear weapons. And of this date the USA and Russia both have a first-strike policy if they feel they have no other choice.
On a positive note the US intelligence just made an announcement that they have no proof of Russian involvement of taking down the aircraft.
"There won't be a Perry Mason moment" is how it was described.
This is probably because Europeans aren't on board with more sanctions and they want to give Putin a chance to save face.
