Maybe, but do you have a better solution?
The problem I think needs a solution is a group of mostly good people being riled up with the well-studied herd mentality, laced with people doing bad things. You want to be able to stop the few bad people (without killing, obviously) with minimal disturbance to the good people, but at any time you cannot know who is good or bad (i.e. you can't enter the crowd to target specific people), and at any point the good people can turn and become malicious actors, contrary to how they'd behave in most circumstances.

the secondary better option is to move away from colonial ambitions where those same vassal states exist to give the US their resources, and must be controlled to doing so, into having their own economic prosperity.
half of this strategy has worked well with mexico already, such that a lot of the southern border immigration isnt mexicans anymore, after nafta destroyed the mexican farm industry and moved the corn to iowa
