During World War II when the Nazis occupied a large section of the western part of the USSR, Heinrich Himmler considered various methods to help control the indigenous population. Alexander Dallin reports in his book GERMAN RULE IN RUSSIA 1941-1945—A Study of Occupation Policies, page 616:
“Himmler conceded that the Easterners needed some general system of values, but it was madness to spread Nazism among them, and to revive the orthodox or to promote the Catholic Church in the East was dangerous. He believed the solution consisted in cultivating those religious sects which preached non-violence. Thus he would spread Buddhism 'among all Turkic peoples'--i.e. Moslems! Among the Christian Slavs, he would promote the teachings of Jehovah's Witnesses [Bibelforscher], whose members within Germany had been confined in Nazi concentration camps. They would be suitable because, he believed, they were pacifist, 'anti-Catholic' farm hands who neither drank nor smoked. Hence—in July 1944—he urged Kaltenbrunner to start screening the inmates of German concentration camps to find suitable 'bible students!'”
Unfortunately for Himmler, by late 1944 the German Army had been evicted from Russia and the Red Army had invaded Germany. So his JW missionary plan probably came to nothing.
Surprisingly the Watchtower has never mentioned Himmler's possible use of the JWs to help subjugate the Russian people. Though in view of the poor relationship between the present Russian government and the Watchtower, I'm sure the JW Governing Body would prefer that the book be closed.
