The Russo-Spanish War (Atlantic Iron Curtain)

This was a brief war between Franco and Khrushchev, which results in Spain signing the Berlin Pact.

Opening moves
NKVD intelligence (under new management) inform the USSR that Nazi war criminals are hiding in Spain. The Soviets give the Spanish an ultimatum: hand over the Nazi officials or face a war. Franco refuses.

Pact forces march through the Pyrennes.
