Okay, random thought, but while Japan was obviously going to be screwed at the end of the war, they did manage to get a lot of fire balloons launched at the US. IOTL, the balloons didn't actually cause any significant damage, but they came damn close, one of those balloons nearly had a lucky direct hit at Los Alamos. Given that the fire balloons made it as far east as Detroit, what would happen if say, the balloons landed and actual started decently effective fires at either
A. Los Alamos (something that would cause actual damage to the nuclear program)
B. Detroit, bonus if it's some of the major auto works which are building things
C. Chicago or Los Angeles
D. anywhere else, but actually causing a number of deaths too high to cover up in the press.
