@hawkeye10,
"How far down can this once superpower dissolve? ....."
The last time we were a superpower, we had a bunch of Hooray Henry Officers in places such as Singapore, who honestly thought that the Japanese would be swatted away like a bothersome fly.
Then WW2 came along and bankrupted us. Our empire soon broke up and we ended up being reduced to owning The Isle of Wight, and being liked by the people of the Falklands.
It is people in British politics today who pretend that we are still in the big league which causes this country to get involved with illegal wars in Iraq, and other such follies.
Britain did more than its fair share to ensure that Europe defeated tyranny, and it broke us, but makes me proud all the same.
The outcome of the Scottish referendum hasn't weakened Britain. In actual fact I believe it's strengthened us, as we will now hopefully become a bit more modern in our ways of governance, and fairer with distribution of power.
When you think about it, where else in the world would a country of millions vote to stay in such circumstances?
It just demonstrates that Britain has a hell of a lot going for it, imo.
