Ahora encontré unas en inglés, con varias que parecen estar mejor traducidas que las anteriores:

Only in the Roman Empire and in Spain under Arab domination has culture been a potent factor. Under the Arab, the standard attained was wholly admirable; to Spain flocked the greatest scientists, thinkers, astronomers, and mathematicians of the world, and side by side there flourished a spirit of sweet human tolerance and a sense of purist chivalry. Then with the advent of Christianity, came the barbarians. Had Charles Martel not been victorious at Poitiers—already you see the world had already fallen into the hands of the Jews, so gutless a thing Christianity!—then we should in all probability have been converted to Mohammedanism, that cult which glorifies the heroism and which opens up the seventh Heaven to the bold warrior alone. Then the Germanic races would have conquered the world. Christianity alone prevented them from doing so.

I am quite sure that very few of the so-called Reds in Spain were really Communists. We were badly deceived, for, had I known the real state of affairs, I would never have allowed our aircraft to bombard and destroy a starving population and at the same time re-establish the Spanish clergy in all their horrible privileges. (10th February 1945)
The Political Testament of Adolf Hitler (1945)

In the Spanish people there is a mixture of Gothic, Frankish and Moorish blood. One can speak of the Spaniard as one would speak of a brave anarchist. The Arabian epoch—the Arabs look down on the Turks as they do on dogs—was the most cultured, the most intellectual and in every way best and happiest epoch in Spanish history. It was followed by the period of the persecutions with its unceasing atrocities. 1 August 1942
Hitler's Table Talks (1941–1944) (1953)

You know my opinion of Franco... We ought to keep these Red Spaniards on the back burner... They're lost to democracy, and to that reactionary crew round Franco too... I believe you to the letter, Speer, that they were impressive people. I must say, in general, that during the civil war the idealism was not on Franco's side; it was to be found among the Reds ... one of these days we'll be able to make use of them... The whole thing will start all over again. But with us on the opposite side.
