It was a classical American terminology: the State Department don’t tell American citizens to stay away from Europe, it just ask them to be careful and try not to identify themselves as Americans.
I could have joined the little smirk appearing on many Israeli faces in the last few days: “Let’s see how liberal are these Europeans when they will have to think twice before getting into public transportation”‘, or “what do you think about a Palestinian state when you have to interrupt every sip of your coffee to look for suspects”.
But I will not. This all drama is played to me more like: “Dear adventurers, America really needs your money. Stay at home”.
