If one views the Israel-Palestine situation through the lens of occupation, then Israel is in extreme violation of international law for transferring its own population into occupied territory and for extreme human rights abuses against civilians. In this scenario, the US should not grant Israel impunity and should not restrict efforts by the UN and international community to punish Israel for its actions.
If one views the Israel-Palestine situation through the lens of annexation, then Palestinians have as much right to use self-defence as Kuwait during Iraq’s attempted annexation of the region. Like Kuwait, Palestine does not have sufficient means to defend itself. In the situation of annexation, the international community should be giving Palestinians the same level of (ostensible) moral support they afforded to Kuwait.
If one views the Israel-Palestine situation through the lens of apartheid, then the international community should apply the same pressures to Israel that they applied to South Africa.
In all three situations, the US should (minimally) withdraw the impunity it affords Israel, stop restricting efforts by the UN and international community to hold Israel responsible for its actions, and stop funding Israel.
Noam Chomsky on specific short-term objectives to focus on in a scenario that popular support for Palestinians finally forces a shift in US foreign policy on the issue:
In these and other areas there are important tasks of education and organization that have to be addressed seriously if US policies are to be shifted. They should lead to actions focusing on specific short-term objectives: ending the savage and criminal siege of Gaza; dismantling the illegal “Separation Wall,” by now a de facto annexation wall; withdrawing the IDF from the illegally annexed Golan Heights and from the West Bank (including illegally annexed “Greater Jerusalem”), which would, presumably, be followed by departure of most of settlers, all of whom, including those in East and expanded Jerusalem, have been transferred (and heavily subsidized) illegally, as Israel recognized as far back as 1967; and of course ending all Israeli construction and other actions in the occupied territories. Popular movements in the US should work to end any US participation in these criminal activities, which would, effectively, end them. That can be done, but only if a level of general understanding is reached that far surpasses what exists today.
