Stories of the use of this sort of non-violence occur in our press every day, as they find their way out of the occupied countries which are opposing the Nazi invaders with every means at their disposal. In these countries the vast majority of the people are agreed in their determination to rid themselves of Nazi control. Such common agreement is the first requisite for the success of this method of resistance. When the people of the territory refuse to inform the police about individuals who are committing unlawful acts against the invaders, it is virtually impossible for the latter to check the expansion of non-cooperation or sabotage. Similarly, if the whole population refuses to cooperate with the invader, it is impossible for him to punish them all, or if he did, he would be destroying the labor force whose cooperation he desires, and would have defeated himself in the very process of stamping out the opposition to his regime. Hitler himself has discovered that there is a difference between military occupation and actual conquest. In his New Year's proclamation to the German people in 1944, he attempted to explain the Nazi reverses in North Africa and Italy in these words: "The true cause of the difficulties in North Africa and the Balkans was in reality the persistent attempts at sabotage and paralyzation of these plutocratic enemies of the fascist people's State. "Their continual sabotage not only succeeded in stopping supplies to Africa and, later on, to Italy, by ever-new methods of passive resistance, thus preventing our soldiers and the Italians standing at their side from receiving the material wherewithal for the conduct of the struggle, but also aggravated or confused the situation in the Balkans, which had been cleared according to plan by German actions."[29] Opposition to the German invader has taken different forms in different countries. In Denmark, where there was no military resistance to the initial invasion, the subtle opposition of the people has made itself felt in innumerable ways. There are many stories such as that of the King's refusal to institute anti-Jewish laws in Denmark on the ground that there was no Jewish problem there since the Danes did not feel themselves to be inferior to the Jews. Such ideological opposition makes the Nazis angry, and it also makes them uncomfortable, since they do hold enough values in common with the Danes to understand perfectly the implications of the Danish jibes. Such psychological opposition merges into sabotage very easily. For instance when the Germans demanded ten torpedo boats from the Danish navy, the Danes prepared them for delivery by taking all their guns and equipment ashore, and then burning the warehouse in which these were stored. The Nazis even forbade the press to mention the incident, lest it become a signal for a nationwide demonstration of solidarity.[30]
