I guess you missed the part that talked about the Soviet invasion thru Alaska stalled out in Colorado, Denver was under siege. Did you miss that part?

"The film depicts a fictional World War III centering on a military invasion of the United States by an alliance of Soviet, Warsaw Pact, and Communist Latin American states."

Did you miss that part?

Nope. The main protagonists were Cuba and Nicaragua.
Russia was simply ancillary to the main plot line.
