President Joe Biden says he will not supply offensive weapons that Israel can use to launch an all-out assault on Rafah — the last major Hamas stronghold in Gaza — over concern for the well-being of the more than 1 million civilians sheltering there.
AFAIK Other stuff has gone forward but they’re specifically holding back the large bombs that caused so much death in the rest of Gaza.
Now though we have the problem of Israel holding all but one border crossing closed. (Unless they’ve reopened some in the last 24 hours) Aid is not getting through at all right now. The single border crossing is in the North of Gaza where they’re already in a Famine. The With now has no aid access by ground. It’s all ship stuff, but the ground access is actually far better. There’s also the problem that Israel will not let aid groups import fuel and with the borders closed they can’t drive trucks in to unload the ships.
So the new position has to be either Israel lets aid in or the US steps out of the way in the UN security council.
