From a tiny, cold, wet little miserable island, Great Britain conquered a quarter of the world.
We had the largest, most wealthy Empire to date.
Also, I'm amused that the States haven't learned from History; the Soviets couldn't hold Afghanistan, We couldn't, the Romans couldn't, Genghis fucking Khan couldn't. It's a big desolate strip of NOTHING.
The UK IS WAS the centre of the world - you set your clocks by our timezones, you trade in our language - you use our frontend for the internet, www. The first Turing Complete computer was invented in the UK - Hell, Alan Turing was British. We invented the Car, Train and the Tank, the Passport and the Telephone.
Sure, we're arrogant bastards, but we have a whole list of reasons to be.
Oh, and that map is fucking retarded - why the hell does it split Asia down the middle? Stupidity.
