Despite an officially anti-Zionist stance, Stalin’s government endorses the partition of Palestine in order to terminate the British presence there, hoping to expose the area to Moscow’s influence.

Beyond political support for a Jewish state, Czechoslovakia, a Soviet Bloc member, supplies arms to the nascent Israeli army during its War of Independence. (source)
