They have a choice - only one choice in fact - reject diversity to have peace, freedom and prosperty.
Or, embrace diversity and have war, tyranny, and possibly a Moslem takeover.
This is true. Americans have always been a varied group of people who share similar values, but have not much background in common. Europeans typically care more about their shared background than their current values.
I think that's one of the reasons that the US has such bad press in other countries. Americans just can't understand why ethnic background matters, but the growing number of illegal immigrants is sure changing that.
LOL. America has been at war without a break since 1941. Since 1941, the US has had military operations somewhere in the world.
There's good and bad in that. Bad because the last time they brawled, they shoved a lot of innocent people into ovens. Good because Western arms and military organization were developed in that shark tank called Europe over the span of a few hundred years, and proved so successful that most militaries worldwide attempt to pattern themselves along those lines.
