It's seems obvious that the better plan would be getting military on the side of the citizens and not the fascists rather than driving the military towards the fascists.

That's the better plan, as long as they're willing to denounce American imperialism. If criticizing the imperialism they're cooperating with is enough to push them away, then they're less than worthless as an ally. Also some of us aren't American and don't care about the health of liberal democracy in your murderous neocolonial empire.
