Hamas' iron-tight grip on Gaza will be difficult to loosen, even with Israeli action against the group's leadership.

In Gaza, the only place to buy an alcoholic drink is at the UN beach bar. Hamas has violently shut down all other watering holes to conform with Islamic law. Women in Gaza today wear traditional Islamic dress, a marked change from just a few years ago. Hamas has systematically shaped Gaza into a religious Islamic enclave -- very different from "cosmopolitan" Ramallah.

In Gaza, Hamas has a social services infrastructure that USAID, UNWRA, UNESCO, etc. can't beat unless they are massively re-funded, and even then it will take time.

Can the UN take over Hamas' social services activity in Gaza as Israel disassembles the military wing? Don't know.
