There are lunatics in the US who seem to have completely forgotten the 1300-1400 Israelis killed by Hamas just last year, but who can see the human disaster in Gaza. I don't think those people are so politically engaged on that single issue that they deliberately stayed home from the polls and let Trump win ... in order to ... help people in Gaza? I could be wrong, but it doesn't seem to fit together.
EDIT: To be fair those same folks are notorious for shooting themselves in the foot. So who knows?
EDIT 2: Some of the lunatics above are probably anti-Semitic, despite Trump's claims that they are anti-Semitic. But again how does that drive them to help Trump right now?
More like the two things aren't even remotely in the same ballpark. Imagine if the US had surrounded Baghdad and intentionally starved the residents. And even that example still fails to account for some of the context.
For the record I don't doubt for a second that the same people who protest against Israel now would also have been among those campaigning against the US at the time.
Some people truly try to protest all the horrors of war on all sides, everywhere. Others try to make "Country X" sound worse than anybody else. I don't have your insight into who has what agenda.

Supporting Israel, including acknowledging their right to respond militarily to terrorist attacks, is one thing. Falling deeply in love with Netanyahu's current policies is another. Freaking out and caring only about Hamas is ... a third thing.
