The Iran deal is a victory for Israel, leaving her the only nuclear armed power in the Middle East. The fight between Democrats and Republicans is a game. When the Democrats succeed, it makes it look like a setback for Israel. The idea of a two-state solution, which would leave the Palestinians as ethnically-cleansed as they are now, is fiercely opposed, so if it is ever implemented, it will look like a massive concession by Israel. Both US parties are completely subservient to the Lobby. Their only dispute is which policy best serves Jewish interests.
