Our government has pushed its tentacles. Most US Americans would rather we mind our own business and focus on improving the climate and our health and well being. There are exceptions and some real crappy US Americans. Just like the AfD or the Nationalists in France or Swiss Peoples Party or Finns or various Freedom Parties of Europe. We are not unique over here, but there are many disenfranchised voters (targeted by republican dubious laws) that were not able to exercise their right to vote and that made it seem like we are all ignorant over here. We are not. There are millions of people protesting and organizing. State news and corporate owned news outlets aren’t letting the world know.

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.
