“Despites its denials at the time, the Soviet Union was intimately involved in the Korean War. The contribution made by the Soviets was vital. They provided diplomatic support, strategic and grand tactical planning, including the planning of the invasion of South Korea, and essential logistical support.

Yes.
Ukraines are not fighting this war alone. They would have lost by now if they were along.
