We now have Israel's explanation for killing seven World Central Kitchen workers earlier this week. In brief: drones followed the WCK trucks from a seaside jetty to the WCK warehouse. The Israelis knew exactly what they were. They also saw several cars join the trucks along the way, but they didn't realize they were part of the convoy. They figured they were Hamas soldiers commandeering an aid shipment. So after the food was unloaded and three of the cars headed south, they fired off three missiles and destroyed them.
This doesn't entirely make sense, but even if we take it at face value the conclusion is obvious: Israel should be providing military escorts for aid shipments. That would prevent misidentification and it would prevent Hamas from stealing humanitarian aid.
But Israel declines to do this. Too dangerous, I suppose. They prefer long-range killing. And it would take a thousand or so troops away from their prime mission of killing anything in Gaza that moves.
If President Biden is (a) serious about holding Israel to account, but (b) still supports Israel's goal of wiping out Hamas, then he should insist on military escorts for aid shipments, something Israel has never been willing to do. What other answer is there?
For that MF above: I posted in the thread all links to the citations from my quoted text, which came from here, but the site software has flagged it for too many links.
The source material, which is what you should be more concerned with, was listed at the bottom. In the quoted text you can see numbers in square brackets (eg "[7]") which indicates that the source for that assertion or quote can be found at the bottom, labled as eg. "[7]".
