We're inteligant and skilful.
I'm sure you are.
We've won both world wars.
You also signed a non-aggression pact with a nation where stringent anti-communism and aggressive expansionism were at the heart of its political philosophy and then got invaded by said nation. Gee, I wonder why.
The day someone would win the war over Russia will be the end of world, 'couse Russians are to proud to lose alone.
I'm sure the same was said about the collapse of the Roman Empire and the British Empire at some point. But we're still here.

Anyway, it's bullshit to argue that your country is the best in the world when everyone else says the same. Looks like you have some sort of superiority complex or something.
