There is no way, period, that any lasting settlement between the Israelis and the Palestinians—including one that requires the painful removal of a substantial number of Israeli settlements from the West Bank—will be credible without third-party backing. The United Nations is useless for this purpose, so the only creditable guarantee is an alliance of Western nations led by the United States. Here, the death of Pax Americana is taking its toll. The Israelis and the rest of the world know that the United States will not be a credible guarantor of any peace so long as President Obama remains in office. Such is the legacy of American foreign policy in Syria, Iraq, Iran, Russia, and the Ukraine.
Thus Richard Epstein.
Whose book on constitutional law, The Classical Liberal Constitution, is superb. And thus almost too damn depressing for me to finish reading.
