Of the non-English speaking countries I've been to, everyone I talked to spoke English. Some spoke broken English, but I was able to understand them perfectly fine. English is the most widely spoken language in the world.
Interesting bit of trivia:
When a flight from Russia is landing in China, in what language are the Russian pilot and Chinese people at air traffic control speaking to each other?
They are speaking English.
When a flight from Rome, Italy is landing in Venice, Italy, in what language are the Italian pilot and Italian people at air traffic control speaking to each other?
They are speaking English, too.
