Franco saved Spain. He also saved 200,000 Jews from the Gas Chambers during WWII....but the lefties who work overtime to besmirch his good name will never tell you that.
He was also our ally in the Cold War against the Soviets. He agreed to let Eisenhower put American military bases in Spain. How did he treat his dissidents? Did he kill them or did he allow them to leave Spain? Did he treat them any worse than the Soviet government treated their dissidents? I know of no “iron curtain” that prevented anti-Francoists from escaping to either Portugal or France.
