I'm not confident,” Trump told reporters. “That's not our war. It's their war.” He said that his administration “might” help rebuild Gaza, which he compared to a “massive demolition site.”

President-elect Donald Trump's incoming national security adviser, Mike Waltz, said on Sunday that if Hamas reneges on the Gaza ceasefire-for-hostages deal, the United States will support Israel "in doing what it has to do.

Analysts say the fragility of the truce agreement and escalating violence in the West Bank threaten US efforts to normalise Arab-Israel ties.
