Trump’s tweet came about an hour after The U.N. Security Council passed a resolution demanding an end to Israeli settlement building in occupied territories.

The U.S. had the ability to veto the resolution but abstained from doing so despite pressure from Trump, Israeli Prime Minister Benjamin Netanyahu and U.S. lawmakers.

The Obama administration’s decision to let it pass represents a break from the longstanding U.S. policy of shielding Israel from U.N. reproaches.

Israel’s settlements are seen as human rights violations, and some say they are an obstacle to achieving peace between Israel and the Palestinians.

Trump pressured Obama before the U.N. vote to veto the resolution.

"As the United States has long maintained, peace between the Israelis and the Palestinians will only come through direct negotiations between the parties, and not through the imposition of terms by the United Nations,” the president-elect said in a statement Thursday.

"This puts Israel in a very poor negotiating position and is extremely unfair to all Israelis."

“One cannot simultaneously champion expanding Israeli settlements and champion a viable two-state solution that would end the conflict,” she said. “One has to make a choice between settlements and separation.”
