 Gjems-Onstad expressed his outrage at the Lund Report in 1996 after it was revealed that he had been under surveillance by the Norwegian Police Security Service (POT), considering it defamatory and demanding an apology.Gjems-Onstad came to believe that the recent mass immigration to Norway was a greater threat than the Nazi invasion of Norway, although he made clear he had nothing against "normal immigration" and individuals, nor about Norwegians finding spouses in other countries.What he stated he was concerned about was increasing ethnic tensions and Norwegians being outnumbered in Norway in the course of the 21st century, and he stated that what worried him the very most was the growth of Islam.
