When they had served their purpose, they were dealt with after Hitler sold out to the Deep State.
Those little happenings also occur in commie revolutions. Many of the useful idiots become dead idiots.
Our very own useful idiots have no idea what’s in store for them if they can get this country to go full commie. A new regime does not want trouble makers which means the neighborhood BLM Antifa pukes will be toast.
Once they outlived their usefulness, Hiltler drummed up charges of treason against them, had the leaders of the SA rounded up, along with many others he perceived would potentially get in his way, had them killed, or were given the option to kill themselves. Hitler got rid of anyone he felt could jeopardize his future, and specifically eliminated people who weren't comfortable with some of the things he wanted to do. Tyrants can't stand opposition from anyone, and won't tolerate it. There's been plenty of tyrants throughout history, and many of them are alive and well in the U.S.A. today.
