I agree with what you are saying, but want to clarify the example a bit. Yalta is in fact in Crimea, I believe most people there would ask you to not call their land part of Ukraine (note: this doesn't mean I believe that annexation was a good idea). They probably don't have cruise ships there, most tourists are from Ukraine and Russia. If Russians won't be able to go to Turkey this summer (almost sure) but will be allowed to go to Crimea (we'll see how that goes…), this major part of Crimean economy might be actually in better shape than before.
