Who is in charge of Gaza's future?

After all the razzmatazz and the wonderful sight of the hostageas being handed over to their families, you do have to ask: what happens now? Who is actually in charge of making sure that the next phase of the Donald Trump peace settlement is put into action? Not Trump, presumably. He's back in Washington and will have lots of other things on his mind and in his in-tray. Not Marco Rubio. As secretary of state and national security adviser, he also has other things to worry about. Will it be Egyptian President al-Sisi, or the Qataris, or Turkey's President Eerdogan? There's talk of having an Arab peace-monitoring force in Gaza, but that is nowhere near off the ground yet? Then there's the Trump-chaired board to oversea Gaza's future but that isn't set up and, again, no one is specifically in charge. It can't be the Israelis because they are supposed to be withdrawing in stages? It's not going to be the UN because their only role is humanitarian right now. So who is at this very minute rushing around getting phase two sorted out? I haven't a clue and I have a bad feeling no one else does. If this peace deal is going to work it will need a huge momentum of decision-making and negotiations. Meanwhile, law and order in Gaza is left to Hamas and the assortment of militia who are like street gangs. I just feel desperately sorry for the Palestinian families who have been promised peace but still don't know whether they are safe to return to their homes, or more likely the rubble of their homes. Who is in charge?
