The media seems to like to create this image of islamist terrorists spreading throughout Europe and taking over. It's not like that. I speak as a European. Yes, there have been terrible tragedies in both Paris and Brussels. But what about Yemen? Afghanistan? Pakistan? Iraq? Syria? Turkey? They have far more terrorism in their countries than any European country, Back in the 70's and 80's the UK was a target for the IRA... terrorists under a different name.
Europe is probably a far more peaceful place than the US. Take a look at the statistics.
Rural areas of Europe are wonderfully peaceful. Don't be afraid to come. It's what the terrorists want. Don't let them win!
