It wouldnt ultimately change people's minds about Hamas being terrorists nor Israel's "right to defend itself". You'd see a lot of hate for the Israeli government but not for the right reasons and the US government would still support it for obvious reasons. You'd be likely to see a lot of "bad apple" arguments pinning the blame on netanyahu specifically instead of addressing the systemic problems as usual.

Basically people would hate Israel more in general but it wouldn't push people to support Palestine.
