Secretary of State Mike Pompeo told me in an interview today that the U.S. will support Israeli annexations in the West Bank, as long as they're consistent with the maps presented in the U.S. peace plan.

Why it matters: Israeli Prime Minister Benjamin Netanyahu said he'd bring plans to annex the Jordan Valley and all settlements in the West Bank before the Cabinet on Sunday. He would not have taken such a dramatic step without U.S. backing.

What he's saying:

“We set markers for the things we thought acceptable, and in exchange [for annexation] Netanyahu is prepared to take lands that are demarcated in our maps and hold those for a future Palestinian state."

Pompeo said the Trump plan was the best opportunity the Palestinians would have, and he urged Palestinian leaders to reconsider their decision to reject it, or to perhaps present a counter-offer.

Pompeo warned that Trump's plan could be the final offer the Palestinians receive.

“There is a real offer that sits on the table for the Palestinians — all they need to do is to say yes. We are prepared to begin negotiations based on this vision. We can start the process towards their having the state they always wanted."

Pompeo said he was not concerned that a Netanyahu loss in the March 2 election would affect the viability of the plan.
