As I've suggested the best way to avoid self destruction is to put down the officers in charge. It is very difficult to keep Russia out of the UK even with cooperation. I have serious security warnings & I will active sleepers in place already to kill all commissioned officers if I am their mark locally or otherwise. That way I intend to avoid shooting all of your aircraft on the ground & shaking hands with Russia in a temporary alliance.
The commissioned ranks are filled out with members of any one of a dozen Royal families in the UK. Only Michael protocol are allowed commissions.
