A reflection on something linked by Insty:
The only reason England hasn’t been conquered yet is because the only tribes that still have the will to conquer it lack the technological and material advantages necessary to do so by force. Can you imagine how easy it would be for an imperial power to roll over pretty much all of Europe, for that matter? They’d go down in six months flat, if the US stayed out of the way.
Hmm. That might make for a good Alien Invasion story. What if the Alien Overlords bribed the USA (and maybe China) into staying out of it while they took over running Europe? What if, instead of invading with weapons, they invaded with money and just bought the whole continent?
