The US has a much more potent lever than military aid - its pretty much automatic veto in the Security Council. The whole Goldstone affair has the Israeli government running scared: none of them want to be the first to be arrested in Europe, to which they love traveling (and staying in highly expensive hotels at the taxpayers' expense - this is a recent scandal over here). All the US has to do, to get Israel to move, is to hint that the veto is no longer automatic. No pariah state, which Israel is much as I dislike admitting so, can survive without support of at least one superpower; we can find ourselves under sanctions faster than Iran, and they will hurt more, to boot. So, no need to bring out the main gun. A side battery will do.
