US President-elect Donald Trump on Wednesday shared a video of Professor Jeffrey Sachs insulting Israeli Prime Minister Benjamin Netanyahu.

Trump posted the clip of Sachs, a lecturer at Columbia University, on his Truth Social account without comment.

While Trump did not mention or allude to the insult, the video began with criticism of former US President Barack Obama (Democrat), which suggests why he posted it.

"Since 1995, Netanyahu has had a theory that the only way to get rid of Hamas and Hezbollah is to undermine the governments that support them, which are Iraq, Syria and Iran," Sachs says.

Speaking about Netanyahu, he added: "He is still trying to push us to fight Iran to this day," then directed an insult at him, calling him his mother "because he got us into endless wars."

The Israeli Prime Minister's Office did not comment on this publication by Trump.
