The question is whether the cease-fire in Lebanon that Biden announced Tuesday will be the coda to his diplomatic efforts in the Middle East or a steppingstone to agreements that could at last end the devastating war in the Gaza Strip and potentially even set the stage for a broader regional transformation.

Under the terms of the deal, Israel will gradually withdraw from Lebanon, while Hezbollah isn’t allowed to rebuild near the border. But will the ceasefire hold?

The ceasefire deal in effect could end more than a year of cross-border fighting between Israel and Lebanon's Hezbollah militant group.
