I think in nearly every country in the world ,the overwhelming majority of people want to live in a peaceful and friendly way so it is not surprising that you liked the Russians that you met. In the DR I have never met with open hostility . I feel very confident that 99% of Russians have never heard of the Dominican Republic and if they had heard of the name they probably think we are in Africa!I've been to Moscow, have a few Russian friends and I've never met a Russian I didn't like. No need to bash them. Politics is an ugly sport in any arena.
The fact they are still willing to show solidarity with the Dominican Republic even after the US government forced them to stop allowing direct flights tells me two things. Not only do they understand how America bullies smaller countries into submission, they also value their relationship with the Dominican people.
