I should have qualified that to say that the bluntness and the "serious" expressions are more Slavic in general, and not just Russian. I also encountered it in Poland. In the US, I think we call it "resting b*tch face":
I have been accused of having it from time to time. If you look at my Russian пропуск (from the Soviet era) you can totally see it
Regarding the food drop in Iraq. Interesting you mention that. When I was living in then-Leningrad, there was a state of emergency declared and some American benefactors delivered several cargo planes filled with food. But what I saw were pop-tarts, granola, yogurt, and mostly cheap fast-food type items you would find at the local "Quickie Mart." I don't know what the reasoning behind that is. I don't claim to understand it. People who are hungry need real food! Not crap from 7-11.
