Reasons for such calculations there were substantial: traditional anti-Soviet policy of the ruling circles of England; Munich; Anglo-French war plans against the Soviet Union developed in the autumn of 1939, and finally, the rise to power of Churchill, whose zoological hatred for the Land of the Soviets was known all over the world (Winston Churchill became Prime Minister May 10, 1940). Only the relationship of politics and war analysis provides an objective assessment of the security situation of 1939-1941. The real causes of the events at Dunkirk, failure by the German invasion of the British Isles (Operation "Zeeleve"), the flight to England fascist Fuhrer's deputy Hess can be properly disclosed separately and in their relationship only on the basis of just such analysis. Much quoted in the book B. Liddell Hart facts confirm this relationship, but the author himself does not "see." As a result of the class and beliefs inherent in bourgeois methodology of organic defects, its concepts are constantly coming into collision with reality and does not stand the test of it.
