But I somewhat agree with you. There is a huge disinformation campaign to stop US supporting Israel. Iran/Russia and the rest are working extra hard to isolate Israel and then to be completely overrun by its enemies around. It's similar to the same campaign Russia was spreading to stop NATO involvement in Ukraine-Russia war.
And it's US weapons used all over the globe in bloody conflicts.(others here have already put paid to the myth of Israeli dependence on usa military aid as a proportion of Israeli military spending.)
And US violates its own law in donating this huge pile of murder weapons to this occupying party: Section 502B(a)(2) (22 U.S.C. 2304(a)(2)) stipulates that "no security assistance may be provided to any country the government of which engages in a consistent pattern of gross violations of internationally recognized human rights." https://sgp.fas.org/crs/weapons/IF11197.pdf
B'tSalem/HRW/Amnesty have voluminous records of the said violations.
This fake rhetorical caring about "children being killed in Syria and Yemen wars and currently in Sudan" just do drum up argument for killing of Palestinian children is kinda distasteful.
