The problem with this discussion is that “support” is an ambiguous term. The U.S. government is not a monolithic entity whose parts all act in unison so that it would be meaningful to speak of its support or opposition as a clear-cut matter. What’s more, its ostensible “support” is in many cases qualified, indecisive, badly executed, and attached with monstrous strings (often due to internal conflict within USG itself) so much that it ends up being ruinous for the “supported” party.
To take only the most notable example, the U.S. “support” for the Chinese nationalists against Mao’s communists was, for all practical purposes, equivalent to a prolonged backstab.

Soviet support for the Second Spanish Republic is a good example of this phenomenon.
