"I haven't the vaguest idea of exactly what would be included in the package and which promises to Israel would be kept." Simple logic tells you that every promise that was placed in that "package" was contingent upon Israel accepting that package-deal. So if the USA put the veto in that package (and it did) and Israel refuses to accept that package (and it refuses) then the USA is under **no** obligation to veto **any** UNSC resolution that furthers the creation of a Palestinian state.
