EDIT: no, I don’t sympathize with nazis (neither I sympathize with those who call everyone nazi when they’re losing an argument ;)
If you follow your own link to a list of non-aggression pacts, Wikipedia lists 9 of them, most predating the Molotov-Ribbentrop pact. Other countries were signing these pacts with Nazi Germany. Not to mention the USSR attempted to create alliances with other European powers, but was rejected. The writing was on the wall that war was heading their way..
I can’t read the first link as it’s behind a paywall. The second link talked about how Roosevelt tried to establish cordial relations with the Soviet Union but was hampered by their refusal to acknowledge debts owed by the Tsarist government, refusal to stop spreading propaganda within the US, and the killing of Leningrad Communist party boss Sergey Kirov which " launched the first of the “Great Purges” that led to the death or imprisonment of millions of Soviet citizens as the Stalinist regime liquidated any potential critics of the government. The wide scope and public nature of the purges horrified both American diplomatic personnel stationed in the Soviet Union, and the world at large."
Gee I wonder why the USSR had such a tough go at getting allies…
