Actually, you are wrong.
There is what can be called irrational exuberance, the giddiness that allows people to act with no thought. There was success shooting down a transport. That is a precedent. the other plane is another transport. Precedent says it must be shot down.
In the absence of a command structure the giddiness takes control and the trigger is pulled with no thought...... that’s what we did before. we’ll do it again
I don't disagree with that. I just think that it is incompetent to provide these kinds of missiles to incompetent jerks who lack a command structure. It just underlines the fact that Putin is incompetent. But, anyone who's been to Russia and has experienced the economy that Putin has created knows that Putin is incompetent. He's in way over his head. He'll screw things up in the Ukraine just as he has screwed things up in Russia.
