It probably wouldn't hurt for some of us to eat a little humble pie. My experience in foreign countries, even 50 years ago, was that a lot of people seemed to feel that people from the United States were rather arrogant, even though we are trying to be friendly. Calling ourselves American can really bother people from Mexico, Canada, Central or South America. The people in Argentina called me Estado Unidense (United Statesian) or Yankee. With the Argentine accent, that sounded to me like they were calling my "junkie". Needless to say, I didn't like the sound of that. So breaking the ice wasn't easy. I eventually made life long friends with them, but it wasn't a great way to start.
As far as people from other countries hating our government, especially places like Panama, Canada and Greenland, I can only think to comiserate with them, and let them know that is one of the reasons I'm coming to their country now.
