Thomas Jefferson resorted to the same use of Federal Army and Navy troops to enforce his embargoes in his second term; it was considered a military dictatorship at the time, and should be considered the same thing now when that tactic is resorted to. There are other methods that can be used, just as Madison said when rejecting a clause some wanted to include in the Constitution to allow the Federal government to use military force against a state, a power specifically proposed to be granted to the Federal govt. and then vigorously rejected at the Convention. It was illegal when Jefferson used it and it was illegal when Eisenhower used it. Just because they were allowed to get away with it doesn't mean it was legal to use that force.Black gangs are indeed a problem, but the military doesn't want to do amything about them much, except deny they're a problem, while Biden's racist hack secretary of no defense runs around trying to run off all the white boys in combat units. We know why he's targeting them, of course.
I'm not sure if you realize it but the military does not operate within the US. It has no jurisdiction over gangs, black or other.
The 101st Airborne was sent into Little Rock to enforce integration at Central High School.
And do you know why?
Because the Governor refused to follow the US Supreme Court ruling in Brown Vs. the Board of Education. He refused to enforce or follow the ruling, and in fact called up his own National Guard to refuse to allow integration in schools.
Quite literally, they were a hair away from being declared a "State in Rebellion", and the use of Federal troops was seen as the only way to prevent it from turning into an outright rebellion. First, President Eisenhower nationalized the Arkansas National Guard, then sent them home and sent in the 101st to enforce the Supreme Court decision.
Was it radical? Yes, but then again so was the Governor mobilizing his own National Guard with orders to prevent any integration. And the message to other states considering doing similar things was read loud and clear. Ike would not stand for a state to openly refuse to recognize the ruling of the Supreme Court. And the Federal Troops were only called up because the State had done it first.
In other instances, Presidents themselves called up the Guard and used them similarly, but only used Federal troops this time as a response.
