U.S. President-elect Donald Trump's national security adviser, Mike Waltz, will meet with Israeli Minister of Strategic Affairs Ron Dermer on Wednesday to discuss efforts to reach a Gaza hostage and ceasefire deal and the Iranian threat. Trump has promised to end wars in the Middle East and elsewhere, but has provided few details on his plans. He recently vowed there would be 'hell to pay' in the Middle East if hostages held in the Gaza Strip were not released prior to his inauguration. Israeli leaders have praised Trump's pledge, while the reaction in Gaza has been less enthusiastic. Israeli officials also expect Trump to take a hard line against Iran.
