Maybe, just maybe, it's the continuing support for what the US, rightly or wrongly, sees as a hugely important strategic ally in the Middle East.
Talk of Mossad and Epstein and secret footage of Trump is all very exciting, but it wasn't what led the US to commit to $2.7bn every year for ten years in military aid in 1999. Or to them increasing that to over $3bn in 2010 (unless they had footage of Obama too).
You can go back to Woodrow Wilson and his support for the Balfour Declaration. Truman was the first to extend recognition of Israel in 1948. It was JFK that founded the US/Israel military alliance.
Whatever people think of both of them, they've been closely aligned for decades. This may be one of the more extreme instances of that alliance, but I suspect that's all there is to it.
