In 1939, Quisling turned his attention towards Norway's preparations for the anticipated European war, which he believed involved a drastic increase in the country's defence spending to guarantee its neutrality. Meanwhile, Quisling presented lectures entitled "The Jewish problem in Norway" and supported Adolf Hitler in what appeared to be growing future conflict. Despite condemning "Kristallnacht," he sent the German leader a fiftieth-birthday greeting thanking him for "saving Europe from Bolshevism and Jewish domination". Quisling also contended that should an Anglo-Russian alliance make neutrality impossible, Norway would have "to go with Germany." Invited to the country in the summer of 1939, he began a tour of a number of German and Danish cities. He was received particularly well in Germany, which promised funds to boost "Nasjonal Samling's" standing in Norway, and hence spread pro-Nazi sentiment. When war broke out on 1 September 1939, Quisling felt vindicated by both the event and the immediate superiority displayed by the German army. He remained outwardly confident that, despite its size, his party would soon become the centre of political attention.
