America underestimates the difficulty of bringing manufacturing back

America is not a country, it's a continent. I know, Canada will be a province, and soon Panama of course, but in the meanwhile, it's a continent, not a country.

But famous American themselves call their country "America".

If you search a dictionary for "America", the first result will likely be "The United States of America".
