I did not say that it is not. I just fear that even if both sides would be atheists, the persons in charge would continue to keep up their aggressive and gruel behavior. Just because it suppresses empathy for the humans on the other side. But yea religion is a wonderful tool to fuel hate and convey totally absurd messages.
I am not sure of assholes. I think they distribute evenly across all nations. On the other side those countries tend to be specifically nationalistic. Russia would also go in this cluster, but it is much more seldom to meet Russians these days in Europe or the US. I just want to add that India has the huge advantage that a lot of people can speak some kind of English. Most with a strong accent, but the percentage of English speaking Indians is very high compared to china, Korea, Japan.
