akuperma, agree on most points. If someone gets too concerned about current events, go to the library and open papers from any previous times and see how unhappy and worrying people were.
Of course, what is different now is that we see everything faster. If you read about German population attitudes during WW2 – they do not look different from what Russian population does now: similar attitude that the world is against us, thus we are doing what is needed to survive, and “look what they are doing to us” … any Nazi escalation included “we now call for peace”,” they started shooting across the border”. etc. You may get concerned – “but now you can see events in real time”. Note that German attitudes generally did not change towards the end of the war and shortly after. for example, during death marches from the camps in the last days of the war, Polish villages would generally help/feed the prisoners, while German would not.
