MOSCOW — On one block that is jasmine-shaded the Syrian port city of Latakia, Natalya lives three doorways far from Nina, two from Olga, across a slim street from Tatyana, and a quick stroll from Yelena, Faina and Nadezhda. They all are ladies through the previous Soviet Union who married Syrian guys. Pan off to the more expanse of Syria as well as the amount of Russian spouses grows to 20,000, the individual legacy of the cool war alliance that, starting into the 1960s, mingled its young elites in Soviet dormitories and classrooms.
