From that article the Poll sounds like it was designed to make catching headlines. I mean how many people view any country as "a beacon of hope for the world"? That just seems worded to make for a great headline no matter which way the poll goes.
Same with other questions. I also wonder if they asked them how they define "america" are we talking about how the government acts, how tourists act, how the people act, etc.
This just in, 85% of americans think the brits should visit the dentist.
