I think we know that they won’t. The U.S. has never universally applied it’s ire based on bad behaviour alone, I don’t see why they’d start now.
Why?
Because Israel will continue violating human rights knowing the US will always protect them.
It’s not really human rights violations that drive US sanctions anyway. There’s plenty of other countries that are rife with human rights violations, but don’t get sanctions. So long as they listen when US interests are concerned, they’re fine.
Will the United States Ever Sanction Israel?
No
“Will the United States ever sanction the 51st state?”
lol
It goes beyond that.
With Saudi Arabia leaning increasingly towards BRICS and being more erratic in its support of the West, Israel is the last firm diplomatic beacon and region of influence the US has in the Middle East.
It also just so happens to be an apartheid state.
Even if public opinion sharply turned on Israel (it won’t), the US would still hold firm in supporting it. Not because it’s obligated to Israel or even because of sunk-cost fallacy. But because it would remove any chance of the US playing a part in regional hegemony.
