Ithink that there is nothing worse and terrible than war. in the soviet union the number of victims exceeded 27 million people. the conflict started in 1940.the war was going on from 1940 to 1945.  germany attacked the ussr, june 22, 1941.  this war ended in 1940, in which russia defeated germany.  people who were taken prisoner in the war, were severely tortured, and eventually died.  i think that the conflict can not be prevented, as the nazis made a huge number of murders and did not intend to stop. i believe that all people on our planet must act against wars. we should live as one big family in peace and love.
