While a Palestinian strategic shift may be more likely, it will also be distinctly uncomfortable for Israel and would carry with it unwanted challenges and complications for the United States. It was Israel’s defense minister, Ehud Barak, who said earlier this year that if we don’t get two states then we get apartheid. If the Palestinians were to make that call, then could the United States afford to still stand four-square behind Israel and could it afford not to? Either option will be painful, and for any president it creates a predicament of damned if you do, damned if you don’t.

It is still hard to understand why so many in the so-called pro-Israel camp in the United States (and many Israelis) seem to be willing that moment into being. There are wiser heads in Israel, in America, and in the pro-Israel community inside America advocating an assertive U.S. push for peace, even though it involves taking this Israeli government out of its immediate comfort zone and presenting clear choices that were penned in Washington, DC and not in Jerusalem. But those voices are yet to prevail. The best option is to rip up that old playbook, push a U.S. plan, and lose the squeamishness around deploying U.S. leverage. But time may be running out. Barack Obama may be the last president who can avoid a scenario which is a nightmare for both Israel and America.
