Spain during World War II - Wikipedia

Much of the reason for Spanish reluctance to join the war was due to Spain's reliance on imports from the United States. Spain also was still recovering from its civil war, and Franco knew his armed forces would not be able to defend the Canary Islands and Spanish Morocco from a British attack.

Spanien war von US-Importen abhängig und hätte einige Gebiete nicht verteidigen können. Dazu kam der gerade erst beendete Bürgerkrieg.

Franco war halt vorsichtig.
