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 " . In 1939 , Quisling 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
