In this month, the Paris Peace Treaty was in trouble as we know the League of Nations would eventually die as an idea in the US.   Here is a reference from Oct 13th:

Senator Norris turned from Shantung to a discussion of Korea, where, he said, the Japanese had committed atrocities only comparable with those perpetrated by the Germans in Belgium.  Japan, he said, could not be trusted to keep faith as to the priviliges awarded her in Shantung “any more than she can be trusted in Korea.”

This article from Oct 15th gets into the details of the fight in the Senate and is worth reading in full to get the idea.  The main argument concerns the treaty giving Japan rights in Shantung and Korea is a side note but not really:  Korea comes up as part of the attack on Japan as an imperial power which the critics said the League of Nations and Paris Peace Treaty were meant to protect and empower — which is interesting since people in Korea and elsewhere in the colonial world — where inspired by Wilson’s defense of the idea because they saw it is codifying the right of self-determination…  Korea comes in fully near the end of the article:

“I trust the Senator will throw a little light on the future conduct of the Japanese to the ‘good faith’ in which they carried out their solemn and repeated disclaimers, first, to establish a protectorate in Korea, and then their denial of the intent to annex Korea,” suggested Senator McCormick.

Touche!!

“The only difference is that the Senator from Illinois will leave Japan in a position where she can do in China exactly what she did in Korea.  I propose to bind her to her obligation to return it.”

And if I am not mistaken, it was Japan’s actions in China in the late 1930s that led to the US Congress to embargo key industrial imports that helped lead to the attack in Hawaii and the US entering WWII…
