The administration of U.S. President Joe Biden will make a final push for elusive deals to end the wars in the Gaza Strip and Lebanon, but Donald Trump's election may leave Washington without enough leverage to bend Israel and other regional players to its will before he becomes president.

Senior U.S. officials who have spent months crisscrossing the Middle East for peace negotiations are now likely to face counterparts reluctant to take big steps, preferring instead to wait for Trump's inauguration in January, according to sources familiar with the matter and independent analysts.

Trump has promised to bring peace to the Middle East but has not said how. If his first term is any indication, however, he is likely to pursue a strongly pro-Israel approach, going even beyond the staunch support given by Biden to Washington's top regional ally.
