It all started with the signing of Economic treaty on August 19, which opened the way for Germany to Russian raw materials, that Hitler needed for his expansion plans, and without which all his plans were not really realistic.
And then on August 23, 1939, Molotov, as foreign minister for USSR (with smiling Joseph Stalin standing behind) and Ribbentrop, as foreign minister for Germany signed the Treaty of nonaggression.
Hitler was extremely pleased with it. He needed it as soon as he could and in a private message to Stalin he asked that he arranges the meeting with German Foreign Minister. They met on August 23rd, and the signing happen right there.
The Supreme Soviet (Parliament) ratified the agreement, but they were not aware of a secret protocol. The Protocol specified who gets what and how the Europe was going to be divided. The Soviet Union was getting Bessarabia (now Moldova), Lithuania, Latvia, Estonia, and Finland. Germany was getting parts of Poland and some other territories.
The Treaty was ratified on August 31, 1939, and Wehrmacht (German army) started the war next day, September 1, 1939. The WWII began.
We all know that the Soviet Union fought Germany in the war. But that's not how it started. The WWII started by Nazi Germany with the Soviet Union as allies. Red Army entered Poland territory September 17, and September 22 in Brest there was a military parade of Wehrmacht and the Red Army celebrating the victory over Poland and the transfer of the keys to Brest, which was a Polish city, to the Soviets according to the Secret Protocol.
It was later that the relationship between the best enemies began deteriorating, Stalin started dragging providing raw materials, and Hitler was getting increasingly getting angry, and it all ended on June 22, 1941, when German Armies cross the border of the Soviet Union in what was the biggest military operation in History - Plan Barbarossa.
The Soviet Union has always denied the existence of Secret protocol. They retrieved the German original in 1945 when they took Berlin, and declared the microfilm of the Protocol a fake. I emember Gorbachev saying that there has never been any Protocol, and he kept saying it until 1989, even though he knew about it existence. The Protocol was not good for the Soviet Union.
The troubled part is that today Russia is taking a stand that this Protocol was needed and was the only way the country could protect itself of the imminent war and got nearly 2-year delay, and also by annexing the Baltic republic was able to set the borders way further to the west.
I think it is not easy to find more BS than that. Yes, they got 2 years, but the June invason was unexpected by the Soviets, and the country was not ready for the war. Stalin did not believe that Hitler would do it to the partner.
Moving the borders did not help either as 2 weeks into the war all these annexed territories went under German control.
What it shows, however, is that Russia is on its path to becoming a bigger military and political player, and as usual, no rules or decency. It is all about political convenience, and today the idea of everything done right is warming the hearts of patriots, who betrayed the world 70 years ago. Are they ready to betray it today?
At the time they were talking with Germany behind the scenes, they were talking to Britain and France. It is not clear why they did not get far enough with the West, and whose blame that was, but it is clear that the Soviet Union had chosen Nazi Germany, and this alliance is considered by today's Russia as the right one. A very frightening interpretation. It was bad in 1989, and suddenly it became good today. There is a reason why Russia was always calle "the country with unpredictable past".
Never a shame, just a matter of convenience
Isn't hindsight a wonderful thing? If only they knew in advance what we know now that we can look back.
