The UN condemned the US for its invasion of Panama. From Chomsky.info:
this was an act of direct aggression, and it was condemned by the United Nations,

I don't think it equates with it exactly, but it was, the invasion of Panama was rather striking in that it was the first example of U.S. aggression or subversion in which there was no appeal made, there was no pretext that we were acting to defend ourselves against the Russians or their agents, and the reason was that at that point -- this pretext had never been credible -- but at this point it was beyond the imagination of anyone to invent it. In that respect, it was, we might call it, a post cold war invasion. Beyond that, there are similarities I should say. If -- this was an act of direct aggression, and it was condemned by the United Nations, the United States had to vote against both Security Council and General Assembly resolutions, the United States established a puppet regime which is dominated by U.S. so called "advisers" down to details.
