Israel had been a source of aid for Soviet Jewry since 1948. Then, following the Six Day War in 1967, the Soviet Union cut all ties with Israel.

Lishkat Hakesher, the covert Israeli agency established to maintain ties with Jews behind the Iron Curtain, code named Nativ,, had established a relationship with the Rebbe in New York many years earlier. Knowing of the Chabad activists spread throughout the Soviet Union, Nativ became even more reliant on Chabad’s existing network.

This partnership continued, despite the Rebbe’s strong disagreement with Nativ’s tactic of spearheading the public protests that would eventually morph into the Soviet Jewry movement.

The Rebbe was a prominent opponent of the Western Soviet Jewry movement’s loud and often bombastic protests in support of Jewish emigration from the Soviet Union. Basing his position on his deep knowledge of the Soviet Union and the Russian mind, as well as his contacts within the U.S. and Israeli security establishments, he argued that only quiet diplomacy would have the desired effect on the Russians, who bristled at being commanded to release their Jews in loud confrontations. The goal, the Rebbe would stress in public and even more forcefully in private, was to help the Jews in the Soviet Union both materially and spiritually—both those attempting to leave and those remaining—and not score political points and in this way place the Jews of Russia in harm’s way.

The Six Day War had a deep impact on Soviet Jewry, sparking an awakening of the Jewish soul. Even as waves of emigration brought Jews to freedom, there remained in Russia Chassidim who kept the flame of traditional Judaism alive, including Moscow’s Reb Getche Vilensky and Reb Mottel Lifshitz, who helped a generation of Soviet Jews re-connect with their heritage.
