What reasoning? First of all I'm an American citizen, so I concern myself more with what my country does with my tax dollars than what other countries do, especially within their own borders or in situations that don't directly affect American citizens. I don't believe America's job is global law enforcement. It's like asking an American "why don't you apply the reasoning that President Trump is corrupt to President Ali Bongo of Niger? Why aren't you calling for President Ali Bongo's arrest? Double standard?"
also a problem that the West exists I suspect
It's fascinating that my criticism of the US/NATO bombing and invading and occupying other countries leads you to suspect I have a problem "that the West exists". In your conception perhaps "the West" would cease to exist as such if it were not the global hegemon?
yet not a peep when these regimes torture and kill people by the thousands
Saudi Arabia tortures and kills people by the thousands. If China or Russia invaded Saudi Arabia and attempted to turn it into a client state using the justification of Saudi misdeeds, would you support them? I suspect not, but we're back to "when the US/NATO does it it's good, when US/NATO adversaries do it it's bad" being the "rules-based order" many believe should exist.
