"Despite its poor historical reputation, the League of Nations should not be dismissed as a complete failure. Of sixty-six international disputes it had to deal with (four of which had led to open hostilities), it successfully resolved thirty-five and quite legitimately passed back twenty to the channels of traditional diplomacy. It failed to resolve just eleven conflicts. Like its successor the United Nations, it was capable of being effective provided some combination of the great powers - including, it should be emphasized, those, like the United States and the Soviet Union, who were not among its members - had a common interest in its being effective. Remarkably, given Manchuria's role as an imperial fault line earlier in the century, this was not the case in 1931. So uninterested was Stalin in the Far East at this point that in 1935 he offered to sell the Soviet-owned Chinese Eastern Railway to Japan and to withdraw all Soviet forces to the Amur River. If the Soviets were not interested in Manchuria, it was hard to see why Britain or the United States should be, especially at a time when both were reeling from severe financial crises."
