When the US’s unsinkable aircraft carrier bombs Gaza, that’s the US bombing Gaza. Actually it’s not even a proxy, like when Saudi was carpet bombing Yemen with US bombs. Israel might as well be the 51st State because it could not exist without unlimited US support. It’s just a US outpost.
You’re trying to pedantically dismiss a point on a technicality, but you’re still wrong. What Israel does, the US does. It’s one-to-one.
