The protect part is what I find silliest tbh. If there were still massive internal riots and a very real threat to lives, it carries a little more credibility but still doesn't sit right. But it is essentially saying "protect them from the new government, we don't like it", which isn't their decision to make really.
When I visited the tank museum at Bovington last year they did a cold war demonstration, and part of it was stressing that whilst the west had better advancements in vehicles/technology etc, Russia more than made up for it in numbers. Now if a worst case scenario (god forbid) came up and there was a very real war with Russia... there's been a lot of trade back and forth, a lot of sharing, this difference in tech level is no longer there whilst the numbers still is. This shouldn't be anything that actually needs thinking of, as I would certainly hope it never came to that scale, just something that I pondered. Wars are of course fought very differently these days in general though.
