Ian Bremmer shares his insights on global politics this week on World In :60.

Why hasn't the United Nations insisted on military observers in Gaza?

Well, the United Nations doesn't really insist on things. And when they do, it's usually symbolic. Like they insist that humanitarian aid needs to get into Gaza and it doesn't happen. Or they insist that, there needs to be protections for the Palestinian civilians or that the Hamas needs to let go, release all of the illegally held hostages, and it doesn't go anywhere. So you can insist all you want. Also, keep in mind the Security Council would be vetoing that sort of thing because the US has a veto and they continue to use it on most Israel-Palestine related resolutions.
