The Americans who lightly support Israel aren't bombing anything. They're the ones who get animated by giving the issue name recognition.
While 55+ is strongly pro-Israel, 35 to 54-year olds are moderately pro-Israel [1]. So sure, in 30 to 60 years we might see a demography-driven shift. (Gen Z isn't pro-Palestine as much as more evenly divided.)
One of the strategic mistake the American pro-Palestinian movement made from the beginning was deploying majoritarian tactics. Those don't work if you don't actually have a majority. (This protest is an example of it.) Instead, the movement should be deploying minority tactics in the way e.g. the gun lobby does.

Here is one a year later from the same publisher: https://news.gallup.com/poll/657404/less-half-sympathetic-to...
33% are sympathetic to Palestinians vs. 46% who are more sympathetic to Israel. Support for Israel is the lowest since they started measuring in 2001 and is showing a pretty rapid decline. Among democratic voters Palestine support is actually greater than support for Israel (59% vs 21%). Among the youngest age group (18-34 years old) support is 48% for Palestine vs 31% for Israel.
The takeaway isn’t just the shifting demography it is also a shift in support. More Americans are changing their opinion, away from Israel and towards Palestine. Especially among the Democratic voter base.
In Australia 60% of people view palestine favourably whereas only 39% view israel favourably (ADL 2024 Antisemitism survey)https://www.adl.org/adl-global-100-index-antisemitism
It’s very difficult to disentangle how much the effect is driven by Jewish and Israeli diasporas (and others’ proximities to them) [1] versus outright bias. An Australian paper isn’t going to be held to account the same way the Times will be, arguable from both sides, because the latter serves a larger and more-diverse audience.
