Did you know that 2/3ds of Americans don't have a passport? And those that do are abroad only for vacations a few weeks a year.  European countries are so close together that they people there routinely cross into other countries. And their languages are not accepted common business language as English is.  Now, that being said, I think Americans, and British especially,  fall way short in not learning just 5 common words of the local language of the places they visit.  They think they can walk right up to local and speakie English right in their face.  You got to be careful in Spanish and French speaking areas, because the English are the historic rivals of the Spanish and French and hearing English makes those people feel humiliated.  Asians and Africans look up to the USA and to be able to speakie English makes them feel educated and proud.  To them English is the language of success, of greatness, of scientific genius.
