I do not knew what Garner would do,becouse i do nothing about him.
But let us look at one thing - before WWII, well, well before WWII, there was a wee thing called the Panay Incident. In OTL FDR supressed footage of Japanese airplanes attacking an US warship to lessen public outrage.
The thing is, the United States was ill-prepared for war in 1939, especially in Asia -- had hostilities commenced, the only short term result would be U.S. forces being very quickly driven out of China. It's generally believed that the Panay Incident was intentional but *not* ordered by the Japanese government, which at that time felt that war with the U.S. wasn't in its own best interest either; this was an act of Japanese military hardliners who were trying to force a war.
