A major flaw in the UN system is what he stated. From Haiti to Bosnia to Gaza. If the mission ends, so do the high paying expat jobs. They rely on local employees to do the actual jobs and rarely leave their secure compounds to verify. Their security personnel give little fucks about verification. So your best way in is if a cousin who works there recommends and is the vetting element. The UN sounds great on paper. When you see them operate, like a lot of organizations, you just pour another scotch and say fuck it.
The aid they need is sitting in warehouses in Egypt or if support, Djibouti or Dubai. They don't get a check and then go out and buy the aid they need. Supply chains for some of this stuff takes time. In Gaza they run the schools. So you think they would know what is in the curriculum and it is pretty openly agreed that it was anti-Israel, pro-Hamas material.
I advocated early that there should be a humanitarian corridor run by the Red Crescent from Egypt into Gaza. Food, water, medicine. Reconstruction comes later. If someone in Gaza needs cement and rebar right not they are probably doing ok concerning the basics.
I am surprised it is only 12. If you are Hamas, the UN is the first group you want to get people into.
