Suppose that the Republicans won the Spanish Civil War. After the Fall of France, Germany is most likely to invade Spain, since no way they would tolerate a socialist country right next to the Vichy. Now there are two scenarios at hand: one is that the Nazis successfully take over Spain and install Franco and co as quislings, and the other is that the they get bogged down in the Pyrenees and suffer a humiliating defeat.
Once the war is won, the leftist government in Spain would retain a lot of legitimacy (having resisted Falangist fascism and the Nazi invasion/occupation), and thus would stay in power for pretty long. Things get interesting from here, since we now have a bastion of leftism right in Western Europe, a melting pot of social democrats, communists, Catalan/Basque nationalists and anarchists alike. How would the foreign policy of this overwhelmingly left-wing Spain look like? Outright alliance with the Soviet Union is unlikely, but at least Finlandization by the West is pretty possible. Or there's another possibility is that Spain decides to forge its own path and ally with Third World nations. Could an Western European country - and ironically a imperialist power - ever be supporting liberation struggles in Asia and Africa?
