We went bankrupt decades ago propping up Europe and other failed socialist/fascist experiments. We made the mistake with our generosity/ naitivity and now we are living with the results. We gave away money and free education and technology to anyone who asked or stole it without some much as a thank you. To this day America gives more than any other 5 countries combined to any natural disaster or common defense situations.

I do fit your image of Americans I guess because I stop caring what anyone outside this country thinks years ago I only wish some in this country would stop apologizing for us, I find it insulting as I have nothing to apologize for.

As for isolationism I always for it paradoxical why someone would move from a country that is oppressive or lacks opportunity only to get here and reap the benefits and then try to make us just like the place they left. I it was so good why did they leave to come here?

Say what you want, other cultures may have contributed things along the way but this world would be a much different place ( good or bad is your opinion ) than if we had not contibuted/interfered at all.
