Earlier quoted context omitted.
Nor the hundreds of thousands murder by Israel in a genocide, which is why his strategic analysis doesn't see the gulf states are at risk of collapse if they engage Iran on what is perceived to be on Israel's behalf.
So the US can't help stop a slaughter because they don't help stop all slaughters in the world, is that your logic?
Let's look at a scenario. I'm a local policeman who jails everyone in my neighborhood who steals from others, except one person that I allow to steal anything they want, whenever they want. When a victim of their theft tries to take their property back from the thief, I stop the victim and jail them for theft, because they tried to take what is now the property of the original thief. Some people say that I had no right to jail the victim for trying to take back what was originally theirs from the thief. Other people cite that it is technically theft and that someone else constantly getting away with theft does not mean that the policeman shouldn't stop this current case of "theft". Whenever the victims tried to do it the proper way and report the thefts to me, I did nothing.
Should the society trust me to continue doing law enforcement? Of course not. They should immediately replace me, and if that's not possible, they should exile me and organize themselves into a militia and enforce the rule of law on their own.
Going back to the real topic, USA has no moral right to intervene on the basis of punishing "slaughter" when they themselves are in the business of slaughtering people worldwide if it's in the business interest of its elite, and supports other countries slaughtering if it's somehow to the perceived benefit of the USA's leaders. The rest of the world should never allow it given USA's historical record, even a recent one.
