You are deeply delusional if you think "producing bombs" is the only thing America does for Israel. The states have very deep ties, because Israel is America's primary outpost in the region. "Geopolitical partners" are non-fungible. You can't just say "if the US didn't support Israel, some other country would", that's not how it works, besides the self-evident statement that there would be some state with some ideology with some policies at that territory. For example, from the very start (1967) PFLP fought not just Zionism, but also Western, primarily American imperialism - that's how obvious the connection is.
And I'm not American so I don't even know who Kamala is, but I imagine it's some random genocidal politician that could just as well be replaced with any other genocidal politician. The US supporting an Israeli ceasefire would indeed be a heavy blow to Israel because US interests are the only thing preventing unanimous UN support for a ceasfire, and because the US is Israel's primary economic partner, and under US sanctions Israel's military prowess would quickly dive below the level of Cuba, even lower because of the hostility of most countries of the world towards it. But the "ceasefire" framing is disingenuous as it considers the two sides of the conflict as equals, as opposed to the occupied and the occupier.
Of course, what you are saying would be natural for someone who believes in vulgar economists' favorite "supply and demand" and "the invisible hand of the market" being something akin to natural forces. Luckily, they aren't actually natural forces, but something created by humans, something we can analyze just fine.
