Just read through some of the referenced other thread.
I wonder if American's have such a difficult time relating to the patriotic senses of loyalty and betrayals felt in European countries because we've really been very far removed from the battlefield. The Japanese hit us with Pearl Harbor, but for most Americans, that's out in the middle of the Pacific somewhere. I mean, the only people who are even aware of the Pacific are Californians, never mind some pineapple plantation.
Yet hit two of our buildings in New York and we hold a grudge for years at least against an entire religion.
When we watch British comedy working through issues they still have with Germany, when Greece exhibits so much distrust of Germany, we don't relate to that so easily in America. Some of us might chant USA USA (and anyone who took that chanting here seriously simply doesn't get it) but mostly that cheering is just football.
Though I hear these were flying off the shelves this week in Tampa
