Another war in which we took the wrong side. Thankfully, America didn't bomb anyone into giving up their statehood. We only allowed a bunch of ideologically inspired loons to go over as sacrifice to communist goals.
I've read Orwell's reaction to the left's behavior in that war. He was there fighting on the Marxist side when the utter hypocrisy of the left opened his eyes about to their true nature. "Animal Farm" and "1984" couldn't have been written without the eye-opening experience Orwell had while fighting with the Marxists in Spain.
There was much more to that war than Picasso's "Guernica." Like so much else, we are only given the leftist version of history for that time and place. Hitler's Luftwaffe wasn't the only foreign airforce that participated in the war, though you'd never know it from the offical story from the MSM, et al.
