Are states obligated to protect only their own citizens?

Hello, I have a debate tournament coming up(about democracy promotion in the Middle East if that's relevant) and I've been looking for literature on this topic.

After a quick search on the SEP, IEP, google scholar, and this sub, I didn't come up with anything.

If you can just point me to some works related to the question for further reading I can go from there.

The name of the idea that states have a duty to protect more than just their citizens is known as the "responsibility to protect." A good place to start is Gareth Evans's book *The Responsibility to Protect* and *Responsibility to Protect*, edited by Cooper and Kohler.
