Here we go again, its only a matter of time before the star in this solar system stops working too.
No empire lasts for ever - Medes, Persian, Roman, Greek, Spanish, Portuguese, British.....
Even that great federal monolith on the other side of the Atlantic is showing signs of problems.
Europe will fail, history teaches us that. The only question is when. Some argue for imminent and others bury their head in the sand and say never. Both are probably wrong.
Personally I would say the European empire will be one of the shorter ones.
