LOL..!
I would like to know what exactly experience or qualifications you feel you have that makes you any kind of authority on what "most" Americans know or think about the state of the world outside our borders? Are you some sort of ambassador to the U.S.?
I consider myself pretty well traveled, as are many other Americans on this site, and it has been my personal experience that it's actually the Europeans that are clueless as to what "most" Americans know, think, and feel... In all of my recent travels (since Trump's first term until today) Europeans have a profoundly perverted view of America via their own country's propaganda... In all fairness, it's not just Europeans, but almost all outside of the U.S. who are ruled by socialist governments with left-leaning media are ignorant of these realities...
I have found that most, if not all of my overseas neighbors that I have encountered have a caricature ideology of Trump and his supporters which has been happily provided for them by the far-left media's narrative that is far worse in Europe than in the U.S., if that is even possible... Even the Europeans and other foreign visitors that do come here are most often visiting the deepest blue locations of this country. Any foreigner visiting New York, California, or any of the New England and Pacific Northwestern states cannot say they have truly experienced Americana or know the real American people... Therefore, they have no actual idea of what the majority of most Americans think or feel.
Putting my own "America First" feelings aside, I think you would be pleasantly surprised to find that most Americans (at least those outside of the far-left) are the most unselfish and benevolent people on this planet who care deeply what happens outside our borders even though the rest of the world continues to shit on us at every opportunity...
