I would say that Biden going to Israel is the US parking it's tanks on Netanyahu's lawn.
The US does not want this escalating, it's going to put enormous pressure on Qatar to put Hamas on a short leash, and to see what can be done to change its leadership (I don't see Israel being emotionally able to live alongside the current Hamas set-up, and can see why), and I think that Biden will also be acting as a conduit for some form of political change in Israel.
It's an interesting lesson in power - that power only comes through engagement, and that for all the talk of China, or KSA, or Iran, when the US president comes to town, and parks two US Navy carrier battle groups on your beach, it's time to sit quietly and speak when spoken to....
