It must be remembered that the Spanish Sociaslist P.M. got into office with 42% of the vote. That is less than the 43% that got Bill Clinton elected in 1992 and less than the 49% that got Clinton re-elected in 1996.
This is not about "Spaniards". This is about Leftists. Spain has 'em. We have 'em. Sometimes our side wins and sometimes they win. Right now, a flaming one of ours is trying to win the White House in November.
Franco accepted aid from Hitler to fight the Soviet aided Leftists because that is where he could get aid during the Spanish Civil War. After World War II broke out, Franco paid Hitler lip service but did not let the Germans into Spain or allow them to use Spain to attack British Gibralter. Franco's Spain also declared Sefardi Jews whose ancestors had left Spain 450 years ago to be Spanish citizens and thereby saved thousands of them.
One thing that Franco did do for Hitler is take his most radical Right-wingers and send them off in the Blue Brigade to fight the Soviet Union on the Eastern Front thereby striking back at the USSR while cutting down the number of his most radical elements. If there was one "good" way to help Hitler, that was it.
What's going on in Spain today is the same as was going on before and during their 1936 Civil War. Spanish Communists (e.g. Basques and Socialists) are fighting against Spanish Nationalists.
Back in 1936, American Leftists such as those at the NY Times strongly supported Spain's "republican" communists against Franco's nationalistic fascists. They were pretty much able to set it up such that only the communists received American aid to Spain.
In spite of that aid to his enemies, Franco prevailed.
But unlike the accusations against Franco and unlike Franco's leadership peers (e.g. Hitler, Mussonlini), Franco did NOT want a world war, was not interested in expanding his empire in any significant way, and was actually a friend of Spanish jews all over the world.
