Look, I don't want to be a Europe apologist because the continent does have it's problems, but having moved just to Stockholm, the startup scene here seems to be very much hitting its stride.
There have been relatively big exits in the past five years, there's more money than ever in the ecosystem and people seem to be willing to do more risky ventures than before.
I've got a friend in Berlin in the startup industry who's very bullish in their local ecosystem as well. Neither of these places is Silicon Valley nor will they ever be, but they're both doing pretty ok and you can easily start a company here and have it be pretty successful, even globally.
