Nearly half of them were murdered east of the Molotov-Ribbentrop line, usually by bullets, sometimes by gas. The rest perished west of the Molotov-Ribbentrop line, usually by gas, sometimes by bullets. East of the Molotov-Ribbentrop line, a million Jews were killed in the second half of 1941, in the first six months of the German occupation. Another million were killed in 1942. West of the Molotov-Ribbentrop line, Jews came under German control significantly earlier, but were killed later. In the east, the most economically productive Jews, the young men, were often shot right away, in the first days or weeks of the war. Then economic arguments were turned against the women, children, and elderly, who became “useless eaters.” West of the Molotov-Ribbentrop line, ghettos were established pending a deportation (to Lublin, Madagascar, or Russia) that never came. Uncertainty about the final version of the Final Solution between 1939 and 1941 meant that Jews west of the Molotov-Ribbentrop line were put to work.
