As others said, you'll get by with just speaking English - if you're serious think of what would matter aside from language: a life in Italy will be very different than a life in German, not only the weather but also the work culture. Also think of which countries 'match' your education, being somewhere with loads of jobs in your expertise will make things a lot easier. I'd advise anyone able to move from US to Europe to take a leap of faith - if it doesn't work out and the US has by then returned to normal you can just move back and if it doesn't work out and america didn't return to normal you'll likely be happy at least you got out before it got real bad.
