This has been stated many times and forms a unified strategic concept. So far, Russia has not done that, despite foreign weapons used in deep strikes.

This is precisely the same concept that Israel uses to strike four other sovereign countries (in addition targeting diplomatic and civilian structures) without declaring war, albeit, nobody is really striking Israel the way that UK/US is planning for Russia. Israel's military doctrine in that case is total all out nuclear war (check it).

US has been fighting proxy wars just as much if not more as the other guy. They bombed countries for less than someone striking their territory. Even destroyed several countries which had nothing to do with it.

So, what I do want to know, how is this solving anything, and who is there to benefit from this strategy (of total escalation)?
