It's true. Once upon a time, there was a place called England. One day, it just vanished. It was near the spot where the ancient nations of France and Spain and Portugal and Holland once stood. All gone. I woke up this morning, smoking hole where Canada used to be.
It's spooky, man.
So, yes, I suppose that all nations do expire.
Damn! Same thing happened to China, after a few thousand years. We better watch out.
Try opening a history book, son. Countries are defined by many things, one of which is type of government. You and the China-analogy fellow are apparently unaware that China and England have undergone dramatic government changes.
