Anti-American tourism. I would say it is a mainstream opinion in Europe that American tourists are very annoying. Each country has its stereotypes about each other, usually stemming from WW2, but the feelings against American tourists have the wonderful effect of uniting Europe. Then America elected a president that threatened us first with economic sanctions, then war. Perhaps it is a fault in our characters, but we tend to take against people that threaten us with military action.
