US key security guarantor
The US is expected to be a key security guarantor of the deal.

In remarks from the White House Rose Garden, Biden said: “Under the deal reached today, effective at 4am tomorrow, local time, the fighting across the Lebanese Israeli border will end,”. He repeated the last two words: “Will end.”

“This is designed to be a permanent cessation of hostilities."
What is left of Hezbollah and other terrorist organizations will not be allowed, I emphasize, will not be allowed to threaten the security of Israel again,” he said.

Biden said that US troops would not be committed to the border between Israel and Lebanon, but that “we, along with France and others, will provide the necessary assistance to make sure this deal is implemented fully and effectively.”

The deal follows months of international lobbying from the Biden administration, which had launched desperate efforts to halt the fighting but regularly came up short after promising that a deal was imminent.

Biden-Trump
The signing of a ceasefire comes with less than two months left in the lame duck Biden administration, meaning that the president-elect, Donald Trump, could continue to support or upend the deal when he enters office on 20 January.
