Mother Jones

It's not complicated. Too many of our congresspeople grew up in the days when Israel was well-organized and ruthless enough to send them to the electoral dumpster if there was even a whiff of lack of support, and so they learned the lesson and toed the line. I think the world, and the skill level of Israel's operation, has changed dramatically since then, but as in so many other things, congress haven't learned how it is now, and so a supermajority of politicians will simply do whatever Israel wants.

I do think there's a valid point that if the US government as a unified whole simply told Israel that they could either start abiding by international law or else start buying their own kit, they would after a short period of adjustment figure out a way to solve the "unsolvable" problem which they are currently perennially creating. Because the alternative would be the actual threat to their existence, from much more powerful regional players, that they claim they are suffering under from a handful of pitiful malnourished people throwing rockets. But I don't know that getting the US government to make that realignment is in the hands of any single politician, or simple and easy to do.
