The NKVD from the beginning was a Jewish dominated organization...
December 20 Secret Police
"Cheka, the first incarnation of the Soviet secret police (NKVD), was established on this date in 1917. Many Jews played leading roles in the secret police, and even more fell victim to it.
Jews were not overrpresented in the leadership of the Secret Police until the 1930's and never dominated it (50%+). In the Red Terror Latvians played a more predominant role. Jews were overrpresented among the early Cheka in the Ukraine but that was a regional exception to the general pattern in 1917-22.
“About 40 percent of high-ranking NKVD officers had Jewish nationality recorded in their identity documents,” writes Yale University professor Timothy Snyder in Bloodlands: Europe Between Hitler and Stalin
Snyder refers to the state of affairs in 1935-36. You are conflating it with the state of affairs in 1917-22. You ignorance is glaring.
