Oh, the UK had the Germans by the balls alright - - in their mouths!

I mean, hey, sure, yous got the Irish in NI to kick around and prove you still got something vaguely resembling an impressive scrotal sack to swing, but other than that little bit of 'overseas' acreage, ya ain't got anything left. In 20 years time, all that will be left is rump England, some land centered around London, a city where the only English left are Chavs living in Council Estate housing. BWAHAHAHA
The USSR didn't save the UK, as it was outside the freeze zone which is basically how the Russians 'win' wars (see: Ukraine). If it did come to its rescue, y'all be speaking Russian now, and 1984 wouldn't have been a work of fiction.
