I recently returned from 16 days in Europe, where Germans refer to McDonald's as "the American Embassy". The Golden Arches are everywhere, in every big city and many small towns, along with KFC, Starbucks, and Burger King.
English is the universal language, spoken fluently by young people and just about everyone who deals with the public. Only in small towns and rural areas will you find some people who do not speak our language well.
American television shows are on many channels, and are very popular. (It's hysterical to watch Seinfeld or CSI dubbed in German!)
American cars -- especially muscle cars like Mustang GTs -- are everywhere, even with fuel being as expensive as it is. (Diesel fuel for our rented Skoda Octavia wagon was the equivalent of $8 per gallon.)
People who have never set foot in North America know all about American society, government, and pop culture. They can name many of our elected officials, entertainers, and athletes.
We are the 800 lb. gorilla on the world stage, and since the end of World War II we've transformed Europe...I'm having a hard time understanding how we're getting the short end of the stick in our relations with our allies.
