You have got it completely wrong. You said this: "...Spain was a bit busy, to be fair..." I countered with information concerning Spain's military help to the Third Reich in WW2 - I saw many of the flyers at the Gemeinschaft der Jagdflieger Treffen in Berlin in 1991. That was all.
A few historical things you may want to check out:
The Allies promised the Basques that they would assist them when WW2 was over, given that Franco had supported Hitler in his war. The Basques provided troops, as I said previously, to the Allied cause in the last year of the war, and they were considered to be formidable fighters.
Post-war, the Allies did absolutely nothing against Franco and Spain, going back on their promise to the Basques (probably because they saw the next major threat being the Soviets). Consequently, Franco then got after the Basques, arresting, imprisoning and killing a lot of them. It was this action that led to the formation of ETA, an organisation formed to strike back at the official side of Franco's rule. They did not go after ordinary Spanish civilians, but the officials who were ordering the arrests and killings - I'm not saying that that is right, just that the consequences of one action led to the consequences of another.
Basically, we sold the Basques down the river... Get hold of a copy of 'The Basque History of the World' by Mark Kurlansky if you wish to know more.
Hope this explains things a bit more for you, Clint.
