During the Cold War, it was said that the Soviet Union is the only country in world surrounded by hostile communist neighbors. The Russians just have the knack for making enemies.
Russians are Russians. A few years ago I was in Nha Trang which had become a tourist mecca for Russians and saw many of them and interracted with a few. They seem to be generally unpleasant people all around. The walked about sneering at; the locals and being very impolite in a polite society. When I was walking on the beach with my friend’s wife and his little girl- my goddaughter- we got a lot of disapproving looks and bad English insults. Trang and I thought it amusing.
