I have always thought that the illegal settlements that various Israeli politicians have supported in exchange for political power were just an invasive war by other means. I have yet to read an account where those settlers haven't behaved themselves like new-crowned kings and pretty much treated the Palestinians as less than human. It's not Jews, and it's certainly not all Israelis, but all of them will suffer over the ambitions of a few.
I will add, though, that the role of the US is smaller than many make it out to be. US policy for the most part was simply that Israel has a right to exist and that right has to be defended. And in that they aren't the slightest bit different from a lot of European nations. It's a handfull of settlers and some Israeli hardliners that are escalating the conflict.
