Secretary of State Marco Rubio is kicking of a Mideast tour in Israel on Sunday, as Arab leaders reel from President Donald Trump’s proposal to transfer the Palestinian population of the Gaza Strip to other countries and redevelop it under US ownership.

On Rubio’s first visit to the region as America’s top diplomat he is likely to get a warm welcome from Israeli Prime Minister Benjamin Netanyahu, who has praised the plan, and pushback from Arab leaders, who have universally rejected it and are scrambling to come up with a counterproposal.
