Question

Why did the Soviet Union support Turkey in the Greco-Turkish War?

Answer 1

"One of the main reasons for Soviet support was that Allied forces were fighting on Russian soil against the Bolshevik regime, therefore the Turkish opposition was much favored by Moscow.[1] The Italians were embittered from their loss of the Smyrna mandate to the Greeks, and they used their base in Antalya to arm and train Turkish troops to assist the Kemalists against the Greeks"
