Jeremy Corbyn got shouted at too for taking a similar line in the Commons.
When the shouting starts it becomes dangerous to ask for reason and moderation.
Why the enthusiasm for war with Russia?
But, then again, why the enthusiasm for war with anybody?
Actually, I think I know the answer to that one. War unites the tribe (and ours has been bitterly divided). It gets everybody up in the terraces shouting for the home team. It generates warmth and togetherness. A shared hatred is ever so cosy.
Politicians love operating in this atmosphere. Being a war leader, they think, is a short cut to admiration and acclaim (remembering Churchill and Thatcher, forgetting Eden and Blair.)
Thus far it's working for Theresa May- for whom being in charge (sort of) at a time of shouting has won her the best reviews of her premiership.
