The United States is perfectly capable of performing atrocities without Israeli permission, and Israel is completely dependent on US funding and weaponry, not the other way around. And who's actually ever managed to put a leash on Trump?
I really think this sort of "Israel is in control" thing leans into conspiracy lala land at best, and certain very dangerous and bad territory at worst.
The last two operations in Iran were done on the instigation of Israel. The bunker bombing and the current war. The administration gladly admitted it.
And Israel is, through AIPAC, one of the largest donors in congress. Myriam Adelson, an Israeli billionaire and outspoken zionist, gave Trump $100 million for his campaign. Of course she is outright buying Trump, asking him to support the illegal colonization of the West Bank.

On top of that, evangelical christians, who tend to be radical zionists, are Trump's core voter base and fund directly Tsahal and Israel through donations. You can learn directly from the actors in this excellent israeli documentary:

So yeah, not really a conspiration, it's all out in the open. It's also not just a foreign policy, Trump threatened to end universities' funding if they didn't forbid criticism of Israel and allowed the administration to monitor them. A large part of his aides and government members are also Jewish and zionist advocates, which of course steers the policy.
Jared Kushner even does real estate promotion in the illegal colonies, when he's not sent to fail negociations regarding nuclear enrichment
