Andrew: It’s not that the U.S. doesn’t have the “right” to pressure Israel. The U.S. is always pressuring Israel. And no doubt, for the reason you state, i.e., some believe the U.S. has paid for the right to pressure Israel. But, back to the point: the specific issue here related to the wisdom of conducting foreign policy by giving official U.S. government approval to the efforts of private citizens (the usual leftwing subjects), which conflict with the policies of the elected Israeli government. We don’t normally conduct foreign policy with an ally this way, and didn’t during the Cold War, either., though I’m certainly prepared to be convinced otherwise.
