In the early Obama era, the lib argument for how this is “supposed” to work is that the UN would identify nation-state level crimes about to happen (or in-progress), and then send a coalition national militaries over there to solve the problem. They based this on such positive examples as UN and NATO interventions in Yugoslavia and Afghanistan.
Don’t forget Korea!
