Battle lines are being drawn over Donald Trump’s choice to be Ambassador to Israel.

David Friedman is a bankruptcy lawyer who has done work for Trump. Friedman is a vocal opponent to the long-standing U.S. policy of a two-state solution between Israel and the Palestinians, insulting American Jews who do support it.

When named last week, Friedman said he looked forward to doing his job “from the U.S. embassy in Israel’s eternal capital, Jerusalem” instead of Tel Aviv, where the embassy has long stood, pending a negotiated deal about the status of the holy city.

Trump campaigned on promises to change U.S. foreign policy in the Middle East and elsewhere. What will that mean for the nearly 50 year stalemate between the Israelis and Palestinians and how the United States deals with other countries in the region?
