I think part of the problem can be traced to Chernobyl...tragic consequences all the way around there...rich farmlands and dairylands destroyed..which puts economic pressure on people, which leads to discrimination which might have waned otherwise...which leads to immigration if people can immigrate..forced immigration combined with religious fervor combined with a practice of using them in settlements as human barricades...leads to all sorts of problems. I have not seen this brought up..maybe I am wrong on all counts..just a thought. mg
