Just one little problem, what made you think we ever left it? Just because there was jubilation over the Berlin wall did not really mean a change of attitude by the west. It had won, so it did not need to change obviously, west was best.
might have gone, but "our" side was very much in business. How do you keep our side in business, same way it had been in business for 40+ years, by ensuring there was an enemy.
It barely matters what enemy, the lack of reds under the bed just made room for more unwelcome guests/inventions.
How can you win in politics if you don't have "enemies"?
