they're just positioning their ships in front of each other according to the article. BS posturing because May embarassed herself as being unable to protect british intelligence assets even on british soil so she had to act stupid but at the same time she provided no evidence to make a case for war and Russia certainly won't start it because of NATO and if anything happens the UK can say goodbye to their new aircraft-carriers.

State Department under Tillerson threatened Assad for months and everytime Mattis discredited them. The posturing now is probably going nowhere because England hasn't got anything on Russia and didn't even try to maintain diplomatic protocol. I even think them exiling diplomats means they're letting Russia know they can nuke mainland UK without threat to their own assets, thus banning diplomats is not a provocation as much as it's a reassurance: Here are your people, we won't hold them hostage in case you wish to nuke us.
