Arguably the US Military has been invited by the legitimate government to do much more than this. Can't really compare to Russia. Unless of course you reject the supposed election results coming from Machado side as a total fraud, but that's seems like kind of a niche opinion.
I support just staying the fuck out rather than being an arbiter of "legitimate government", especially on a continent where a storied history means intervention will be undoubtedly criticized no matter how noble. In fact I recall this exact idea being part of Mister New York Con Artist's campaign (not that I myself was gullible enough to believe him).
