Stepping into a raging diplomatic argument, Secretary of State John Kerry on Wednesday staunchly defended the Obama administration’s decision to allow the U.N. Security Council to declare Israeli settlements illegal and warned that Israel’s very future as a democracy is at stake. Kerry, pushing back on Israel’s fury at the U.S. abstention of the United Nations vote, questioned Prime Minister Benjamin Netanyahu’s true commitment to Palestinian statehood, which has formed the basis for all serious peace talks for years.
