By TIA GOLDENBERG TEL AVIV, Israel (AP) — Donald Trump will return to the U.S. presidency at a time of unprecedented conflict and uncertainty in the Middle East. He has vowed to fix it. But Trump’s history of strong support for Israel coupled with his insistence during the campaign that the war in Gaza should end quickly, the isolationist forces in the Republican party and his penchant for unpredictability raise a mountain of questions over how his second presidency will affect the region at this pivotal moment. Barring the achievement of elusive cease-fires before the inauguration, Trump will ascend to the highest office in the country as a brutal war in Gaza still rages and Israel presses its offensive against the Lebanese Hezbollah militant group.
