Of course, exhalation was in order earlier this month, when the remaining Israeli hostages were returned to their families, hundreds of imprisoned Palestinians were released and some aid began to move into Gaza. Mr. Trump deserves credit for applying more pressure on Prime Minister Benjamin Netanyahu of Israel than Joe Biden ever did. Yet there was little clarity coming out of the summit in Sharm el Sheikh about who would administer Gaza, how Hamas would disarm, or whether Israel would refrain from resuming its onslaught or annexing the West Bank. It felt more like a victory lap than a beginning.
