Now, we are sitting in our comfortable homes still and this is for us another thought-challenge about horrible events far away. I condemn all wars, but as nerds continue with the thinking and analyzing, this is not meant to defend any side and especially not to justify any war.
Now then, what you said.
Do you also hold that against all the Germans when they started both World War 1, and World War 2? They did nothing. There was no resistance movement within Austria or Germany of any significance to stop their war machines. People where complacent. How did they get away with it? Would you let Russians also get away with it, if they say they are sorry and have changed?
