There’s a lot of examples, yes in South America too, but the US helped replace or tried to help replace some governments during the Arab Spring. Libya being the biggest example, where the US and its allies imposed a no fly zone to help topple a dictator it didn’t like [0]. It could have done that in other places, but you didn’t hear a peep from the US when those protests were crushed by their governments during the Arab Spring.
Libya is a super super bad example if you're looking for bad US behavior. This is literally the very first sentence of your own source:
> On 19 March 2011, a NATO-led coalition began a military intervention into the ongoing Libyan Civil War to implement United Nations Security Council Resolution 1973 (UNSCR 1973).
Compared to the South America stuff, this is saintly and angelic behavior helping out the world in every way. It's not the US alone, it's a coalition that expands beyond NATO, there's a UN resolution...
In fact bringing this up as a "bad behavior" example proves just how much of a shining city on a hill the US has been around the world. It's been bad, but it's also done lots of good stuff.
I don't think you're understanding what OP actually said. They didn't cite the Libya example as an example of bad behaviour; there wasn't any value statement on it at all. They were saying the fact that they intervened in Libya but not elsewhere was an example of the US intervening when it suits them.
I'm not an expert in US foreign policy so I'll refrain from entering the debate itself, I just think you're not arguing against what the OP is actually saying.
In what way does cutting off the sentence create a contradiction? You'll need to at least point out some words that are a contradiction, or address some of the words in my comment.
