The USSR traded with the United States via Amtorg Trading Corporation since 1924, before the US even recognized the USSR in 1933.

The USSR could have easily minded its own business without seeking to seize land from Poland, the Baltic states, and Romania, instead of pursuing an imperialist foreign policy of aggressively spreading the revolution to the rest of Europe.
