Yep. He was a beloved general, and a man of the people.

IIRC: He fought Congress to get WW1 vets paid what they were owed, when the Congress wouldn't pay the vets (what was essentially a pay advance). People were understandably desperate, due to the great depression. Butler spoke publicly on the vets behalf. Which made him the perfect candidate for the coup.

The plan was for him to lead the vets against the White House and take power, which probably would have been accepted. Especially, given the deep-state support he had. The American Nazis actually won WW2. Consider "Operation Paperclip".

Smedley Butler was a peerless patriot.
