There's another version that presents an alternative reality on which side is responsible for the war. I don't think most British want to hear anything about it.
It's just another one of America's wars that unfortunately both of our countries have become involved in.
When/if it comes, Russia will likely dedicate a 100 megatonner to Britain and maybe a few to Canada.
There's plenty of evidence to show that Russia is responding to a threat from the US Tommy.
Just remember to say Nato too, for the sake of appearances.
