I do not know the answer to this, but I am hoping someone here has some thoughts.
Once the US realized the Philippines could not be held or relieved, did they ever consider deploying and potentially employing chemical weapons? I can't imagine the IJA was significantly well prepared for chemical warfare, and even if they were, this should slow them down considerably.
So, what happens if, in the late 1930s, the US integrates chemical weapons into the Luzon defense plan, and the use of such weapons is considered mandatory from the moment of invasion?
