Argh, you replied before I was done with my laborious edits. I added the State of West Virginia to your selection of re-conquests.
Idaho spuds are pretty good. As for chips, it's not hard to find a British pub in Florida. We have three in my town, all Brit-owned I assume (the accents).
As for where we'll all be in fifty years.. I guess at the least, the writing is on the wall for the decline of US dominance in the world. The sun set on the British Empire, and so it must for us eventually.
But I think we do retain an advantage in our cohesion (even if we doubt it). Our 50 states really are a lot more homogonous than the diverse nations of Europe. You're united enough to be an economic power, but not a superpower.
Russia, India, and China are the real questions for the future. China and India don't concern me as much as some people -- they're so large, they have too much interest in stability to ever stomp around too aggressively on the world stage.
Russia is a different story. I'm very concerned about the fascist leanings of Putinsim. They have capitalism there for sure, but no freedom of the press. And Russia plays a lot of games you don't see the more cautious China doing -- Russia likes to manipulate and threaten other countries with energy supplies.
And that business with the radioactive stuff left everywhere in London was a real outrage. They are an oligarchy, sort of reminiscent of where we were in the late 19th century. But at least we've always had freedom of information, something Putin keeps a tight lid on.
If anything keeps the US propped up as a superpower, I'd guess it's the antagonism of Russia. At the end of the day, I don't think most of the world wants Russia to be the only world superpower (shudder).
