I have wondered for years why Bibi gives in to him all the time.
Knowing Obama and his associates, I assume it is something awful. Threats of some kind.
Probably because in March, about the time he promised neutrality between Israel and the PLO, he indicated that many countries we provide aid to, Israel named, should pay for their own defense. Maybe he didn’t mean it, but I can see why Israel might want a deal concluded, even if it meant giving up important provisions from the past. As others have noted, a future President as well as Congress can easily change this non binding agreement, but with an agreement in place it would probably be more difficult politically to decrease it.
