According to Russian sources, Koval's infiltration of the Manhattan Project as a GRU (Soviet military intelligence) agent "drastically reduced the amount of time it took for Russia to develop nuclear weapons." … Koval was born to Russian Jewish immigrants in Sioux City, Iowa. … George Koval attended Central High School, a red-brick Victorian building better known as "the Castle on the Hill". Neighbors recalled that Koval spoke openly of his Communist beliefs. … He graduated in 1929 at the age of 15. … Abram Koval became the secretary for ICOR, the Organization for Jewish Colonization in the Soviet Union. Founded by American Jewish Communists in 1924, the group helped to finance and publicize the development of the "Jewish Autonomous Region" – the Soviet answer to Jewish emigration to the British Mandate of Palestine then being undertaken by the Zionist movement.” ImmigrationMulticulturalismEspionageEthnic Conflict Author:Wikipedia: George Koval
