Of the current 200 nations in the world, the British have invaded all but 22 of them. The lucky 22 include Sweden, Luxembourg, Mongolia, Bolivia, and Belarus.
@kottke Kind of weird to color the whole USA red there. I don't think they ever technically "invaded" the "USA". There should be a red strip on the northeastern edge of it. We won our freedom and then we invaded the rest of what is the USA.
