The US considers all of LATAM as his own back yard. Why can’t China consider all of Asia as its own back yard?

This is what upsets people, the sheer size of hypocrisy.

The point is that the US has set a precedence on military power around the world. The US told the world that using military power for your own country's benefit is ok to do. So why can't China?

That doesn't mean either side was right, or that one justifies the other. Only that the pot should into call the kettle black.

That is absolutely the implication here.

The commenter's focus on hypocrisy reads to me more like they take issue with the US calling China out for this rather then justifying what China is doing because they aren't the only ones.

My point is that you lose all moral high ground lecturing countries on how they should behave when you're doing the exactly same thing.
