Depends on how you feel about the so-called "Responsibility to Protect": https://en.wikipedia.org/wiki/Responsibility_to_protect

If it applies, one issue is that the UN, as usual, is quick to assign responsibility and glacial in assigning corresponding authority. The mismatch between responsibility and authority is one thing many people instinctively hate about the UN even if they can't articulate it.
