it's hard for an outsider to understand.

That’s probably the only truly accurate part about America in your whole statement.

Prior to the current neo-imperialist period that began in 1945, the US was largely isolationist and non-interventionist.

Many current Americans don’t want to be a “champion of freedom and democracy” as you put it. Have you ever seen what happens if you kick a leg out from under a chair someone’s sitting on? You can’t just take it away all of a sudden.

The decisions and actions made by all parties since WWII have created these co-dependent environments and now it’s becoming apparent why they weren’t such a good idea.

As for thinking about their country, that’s pure speculation on your part as that “at least 50%” you call “proudly pig ignorant” would be about 160 million people.

I’d wager Americans think about their country every single day but they do so from a most impactful to least perspective. They think about it in terms of their local town or city, then state, then country.
