President Donald Trump said Thursday he won't allow Israel to annex the occupied West Bank, vowing to block a move that Arab leaders have also rejected. Speaking to reporters in the Oval Office, Trump said he discussed the issue with Israeli Prime Minister Benjamin Netanyahu and underscored, "It's time to stop." Trump was responding to a question about Israeli officials suggesting in recent weeks that their government could move to seize control of at least some parts of the West Bank, a move that has been floated in response to a number of countries — including key U.S. allies like the United Kingdom and Canada, to recognize a Palestinian state. “I will not allow Israel to annex the West Bank. I will not allow it. It's not going to happen,” he told reporters during an unrelated signing of executive orders in the Oval Office. Trump said he'd spoken to Israeli Prime Minister Benjamin Netanyahu, but said he'd be firm in not allowing annexation, adding, “It's been enough. It's time to stop now.” Trump has long bragged about his close relationship with Netanyahu, but the president has faced pressure from Arab leaders, who have publicly expressed concerns about Israeli annexation. The United Arab Emirates has warned that any Israeli move to annex would be a “red line.” Unlike Gaza, where Israel’s war with Hamas continues, the West Bank is administered by the Palestinian Authority. Israel captured the West Bank, east Jerusalem and the Gaza Strip in the 1967 Mideast war. The Palestinians want all three territories to form their future state. Israel’s current government is staunchly opposed to Palestinian statehood and supports the eventual annexation of much of the West Bank. More than half a million Jewish settlers now live in the West Bank in some 130 settlements. The international community largely views the settlements as illegal and an obstacle to peace.
