President Trump claimed that one of the four living former presidents, Bill Clinton, George W. Bush, Barack Obama, and Joe Biden, expressed regret over regretting not attacking Iran during their time in the White House. The claim was made during a press event at the Kennedy Center and repeated during another White House event. However, these statements have been denied by all four former presidents. The revelation comes as a new report reveals that President Trump has rejected negotiations with Iran and has declined to embrace Pentagon options to deescalate the war.
