If you look at that chart, it even shows partly why. Sympathy for Palestinians didn’t hit above 50% of the democratic party till 2024/2025. Which means those members elected were elected in a time of less than 50% support for Palestinians. Also sanctions as being discussed are made by Congress which has not had a Democrat majority since 2009. So there is not way they could have passed any sanctions the Republicans didn’t negotiate to agree with. (Which those charts show less than 20% of Republicans having sympathy towards Palestinians at all times since 2001). So it would be career suicide for a Republican to vote for such, as their constituents don’t want it.
If it were voted on again now, we would likely see 100% Republican Congress support for Israel and 40% support from Democrat Congress support, which is rediculous… But fairly accurate of how that graph would indicate.
Why would you think they would need to be sanctioned for not using them? China and India both have nuclear weapons and have small skirmishes (granted not as big as this) and we don’t discuss sanctioning both of them for it. I would think threatening to use or using them would be the only scenarios where sanctions would be “forced hand” for lack of a better term.
