From the outset, both states sought to overthrow the system that was established by the victors of World War I. Germany, laboring under onerous reparations and stung by the collective responsibility provisions of the Treaty of Versailles, was a defeated nation in turmoil. This and the Russian Civil War made both Germany and the Soviets into international outcasts, and their resulting rapprochement during the interbellum was a natural convergence.[2][3] At the same time, the dynamics of their relationship was shaped by both a lack of trust and the respective governments' fears of its partner's breaking out of diplomatic isolation and turning towards the French Third Republic (which at the time was thought to possess the greatest military strength in Europe) and the Second Polish Republic, its ally.
