Wrong again! The USSR invaded Poland in September 1939 joining on the side of the Nazis in trying to conquer and divide territory.
That was their entry into the war.
It was not until Germany invaded the USSR in 1941 that the USSR formally joined the Allies in the war against the Axis powers.
Eastern Europe was a war zone from September 1939 with highly disrupted transportation, food supply, utilities etc.
The USSR borders were not truly open to nonessential visitors after September 1939. Internal travel was highly restricted as well, Jews were not free to travel from Moscow or Leningrad to The Ukraine, nor were most ordinary USSR citizens. The Kremlin restricted travel to avoid stirring up nationalism and having insurrections in the individual republics.
I got As in geography and European. World and US history.
Nice try.
