Oh how I beg to differ. The "US or at least NATO" does NOT always intervene in time to stop the stinky shit.
Ask the Tutsis if the US intervened in Rwanda "in time."
How about the little matter of Serbia genocide in Croatia during the 1990s. Let us try to remember what happened there, oh yes NATO intervened to stop the killing of Muslims by Serbians. But too late for many.
Let's go back a little farther. How about the Khmer Rouge in Cambodia in 1970s. Oh yes, no US intervention there.
And hey, how about that war that my grandfather fought in? The one where he was a POW for four shitty years in a camp in Eastern Germany. Why don't you ask a Jew with any sense of history whether the US intervened before the "stinky shit" happened.
There are too many threads on the internet started by ignorant people who never bothered to pick up a history book, but nonetheless seem to have an inexhaustible supply of rancid gibberish.
Too many to answer them all. But you caught me on a good day.
