This may be ASBish, but what the hell.
What if, when General MacArthur was preparing to attack the Bonus Army on the Anacostia Flats in 1932, he has a "change of heart" and decides to use his troops to support their wishes? Would the government give the marchers the chance to redeem their war Bonus? Would they demand more? Or would MacArthur march on the White House and try to seize power?
Just something bouncing in my head right now.
