What on earth are you talking about?
What is it you think I want that is suicidal? Putin to be held responsible by the world for his part is shooting down a civilian airliner? That is not going to cause WW3, not by a long shot. But it may result in the kind of international sanctions that force Putin to stop supporting "separatists" with heavy weapons, training, intelligence, etc, who are attempting to destabilize the Ukraine (because without his boot on the Ukraine, Putin's dream of reassembling some part of the Soviet empire is impossible).
We will talk about this again when Obama is removed from office. Until then you have no clue and no chance.
