It's a popularity contest. A global one. The BBC had a total of 24,090 citizens from 22 countries polled about which countries they thought were "mostly positive" or "mostly negative".
Here's the top five:
The United States was number eight, being edged out by France and the EU (which, uh, isn't a country, but whatever). Could be worse, I guess!
Rounding out the top ten were Brazil (at nine) and India (at ten). Read the full report in the link below, which has a country-by-country breakdown. Fascinating stuff.
Don't worry, America. I like ya. <3
