Soviet War Scare (1926–27)
The Soviet War Scare was a crisis in Anglo-Soviet relations involving a threat of a full-scale war between the USSR and the British Empire and Poland in 1926 and 1927. The conflict is mostly interpreted as a sham by the western historians, suggesting that it was predominantly a product of a Soviet propaganda overreacting to theoretical considerations written by anonymous British military in May 1926.
