In his memoirs, Hans-Ulrich Rudel, states that when they invaded the USSR, the Germans were astonished by the Soviets' lack of preparedness against an attack, and the lack of defensive trenches, fortifications, etc. Instead, what they found were columns of Soviet trucks and other vehicles, ready to roll westward. The Germans were glad that they attacked first, as it was obvious to them that the Soviets would have done the same. That's why the Soviets had such huge losses from the start of the German offensive, and this also would explain why Stalin ignored the repeated warnings about a German invasion, because he thought that he would attack first. Rudel's memoirs were published in the 60's I believe, and I didn't pay much attention to this part of his story when I read it first. However, a Russian author the writes under the pseudonym of Victor Suvorov and is an ex-member of the GRU recently wrote a book, which he claims is based on documents found in the Russian army archives, tells the same story, that Stalin was prepared to invade Western Europe, and that Hitler preceded him by a year or two. So could this be true, and even if Hitler wouldn't have started the war, then Stalin would have done it?
