To show what a joke the League of Nations was, the Nationalists got the league to pass a resolution that condemned Japan's response to the Nationalists' attack as "disproportionate"! So the Nationalists bombed the Japanese naval facility in Shanghai, tried to wipe out a tiny Japanese garrison in Shanghai, rejected Japan's peace proposal, sent four divisions into Hopei Province, and then launched an attack on the Japanese quarter in Shanghai with two divisions, but the League of Nations decided that the Japanese response was "disproportionate." The Japanese were sick and tired of the Nationalists' provocations and attacks and decided that this time there would be no ceasefires, no deals, no nothing, until they had driven the Nationalists out of Shanghai and Nanking.
