On the one hand, sure, the people there should watch out for the possibility that the US or similar tries to get a government satisfactory to them installed if the current one falls.
But on the other hand, it's not like there's any mechanism, in a revolution, to collectively declare "you're not allowed to support us" and have it stick. So if all it takes for a revolution to be illegitimate is the US to declare itself in favor, then the US has the power to delegitimize any revolution it wishes without recourse, which doesn't make much sense.
