Genocide is a terrible thing. But that doesn't mean the USA has any obligation to directly intervene in foreign conflicts. Most of these aren't worth sacrificing the life of a single US soldier, and even when we do intervene it often makes the situation worse. Unless critical US national interests are involved, our actions should usually be limited to sanctions and diplomacy.

Most of the time US sells the weapons used to do the genocide. This time they're just giving them away, and that is what a lot of Americans have a problem with.

We sold weapons to Burma, China, Russia, ISIS, Sudan and Somaliland [1]?
We're absolutely complicit in Gaza, the DRC f/k/a Zaire and Bosnia. And we helped defend the Yazidi and Ukrainians. Honestly, looking at the list, that's a better record than Russia or China have had since WWII.
