Spain is a marginal region of Europe, it took a lot of hard work to become independent from Portugal, and to share the fruits of Portuguese navigation, so that it can be nameless in history, in the traditional European concept, the Spaniards are almost like the Psyches, living by singing and dancing.
Spain, whether politically or economically, as well as geographically, has no urgent influence on the European war situation, and the Allies and Axis powers have no special interests in Spain, so it is mainly a political temptation for Spain, there is no need to open another front, Franco has the operating space to bet at both ends. Just before the war, Franco had just established his dictatorial position in Spain, and the Spanish Civil War that occurred before World War II had almost become a weapons testing ground for the great powers at that time, and both Franco and the republican government had introduced international support and international columns to move, and Franco, the dictator, had also fought, and all had the necessary pragmatic cognition, as the dictator who won the final victory, of course, knew his own family background very well.
In the early stages of World War II, Italy watched the French army being beaten by the German army, ran to take advantage of France, and as a result, its own army was beaten by the French remnants of the army, and the Spaniards, who knew themselves better than the Italians, never wanted to participate in the war, because Franco was too aware of the ferocity of the international column that dominated the Spanish civil war, and the defense of Madrid was fought by the international columns of both sides, and the Spaniards became onlookers, and these international columns were all volunteers for the countries sent at that time. In the eyes of those countries, this kind of battle that could dominate Spain's life and death was nothing more than a bunch of reservists in the family.
A little earlier history has shown that the Spaniards could not even rule the natives of the colonies, so they did not expect to receive victory dividends after the war, and could govern the French or germans, not even the Italians. And the troops that Spain can send out, from quality to equipment, are not even qualified to participate in the First World War, no matter which side they are thrown into, they are only cannon fodder consumables, so only after Germany attacked the Soviet Union, a volunteer division was sent to follow, which is a good explanation, after all, Franco was like Hitler asked for help during the civil war, and the Soviet Union happened to be the main force supporting the Republican Army.
In the development of the war, Italy has already taught Hitler a profound lesson - the more allies, the better, and some allies really want to give to the other side to suffer! Therefore, for the Spaniard Allies, whose reputation was even worse than italy, Hitler was far away from it, he sent people to help Franco, and knew the quality of Franco's army. The Allies also know the quality of Spain, so the requirements for him are honest, don't talk about chaos, no one will think that Spain can provide any help to Germany, just a routine request for political taking sides, just Spain, play neutrality want to drag to see the results and then take sides, everyone does not matter, do not add chaos, do not take the initiative to jump out and punch anyone in the face, then go with him.
So Spain, as a fascist dictatorship, was able to get through World War II, and Franco, as the only fascist dictator, died peacefully until the seventies, but after his dictatorship took office, it was not a fascist dictatorship, but it was more moderate than the general dictatorship, which was quite suitable for spaniards and stable for decades, but as a country in Europe that was basically not affected by World War II, his development was too stable, and when the European Union was established, Spain's main international income was actually greenhouse vegetables The descendants of the brave men of the Great Voyage became vegetable farmers who specialized in providing vegetables for the European market.
