Neo. The Only. The One.
THE ONE
A war with black people would cripple the infrastructure of an Empire. They would win but the price would be too costly just like Vietnam, Iraq and Afghanistan. But on a greatly level because it would be domestic.
Nah its not the economics of it that would cripple the US. It would be the complete loss of total moral standing.
When going to war, there has to be a "justification". Always.
Even when they wanted to go to war with Iraq, they had to do something to somewhat legitimize it.
Even though it turned out to be a lie, at the time America had just been attacked and Sadam supposedly had weapons of mass destruction.
Whenever you go to war, you've got to provide a reasoning otherwise you risk loss of moral standing and rebuke and even possible intervention from other nations.
America would never have been justified in declaring a hot war against the NOI under Elijah Muhammad because he did everything to make sure that Muslims were not seen as a threat, even down to forbidding Muslims to carry weapons.
