economic restrictions? the visa restrictions are a real problem. the largest number of tourists to turkey are germans. russia is the second largest group. it s an important part of their economy. three fifths of turkey s gas supplies come from russia. you might have and i hope you ll have russia sort of toning down the rhetoric in the next few days, that would be helpful. but erdogan himself has pressure. the problem with both these leaders is they are nationalists, they both say i ll make turkey strong, i ll make russia strong. it s not easy for erdogan to back down and not get anything in exchange from russia. given how much is at stake between the two countries, why do you think turkey did what it did, assuming it knew this was a russian warplane? i think it s fair to say there have been dozens of provocations by the russian air force, not just in turkey but primarily against nato
