> Israel sanctioned BYD and China sanctioned Israeli cybersec firms back recently to my knowledge

Yup. China is also shipping arms precursors (and very likely intelligence) to Iran. China and Israel aren't friends. But Israel pivoting from the U.S. absolutely brings it back to the table. China isn't, like, sanctioning Israeli firms in general, or even Israeli firms in the West Bank.

> doubt it'll be straightforward or that Israel would be so aggressively expansionist without the 300 billion or so they've received from the US

My personal hypothesis is the aid turned Israel into a monster. Removing the aid, however, won't change that. It just means more broad-based munitions.

Israel and Gaza have natural gas. The world has shown it will tolerate a lot of nonsense from an energy supplier, particularly a nuclear-armed one.
