The United States and Israel launched their most ambitious attacks on Iran in decades on Saturday in an operation that killed Supreme Leader Ayatollah Ali Khamenei.

The US president has called for regime change following a massive US and Israeli attack, which prompted an unprecedented wave of retaliatory strikes by Iran.

Undermining this moment of relief for many repressed Iranians is that killing Supreme Leader Ayatollah Ali Khamenei is a perilously simple fix to a very complex problem.

President Trump spoke for nearly two hours to a joint session of Congress. President Trump delivered the first State of the Union address of his second term on Tuesday to a joint session of Congress. The following is a transcript of his remarks, as recorded by The New York Times.

In his first comments about Saturday’s US military strikes against Iran, President Donald Trump claimed in a video posted to social media that Iran has been building missiles that “could soon reach the American homeland.

The footage shared by US Central Command on Saturday shows destroyers firing missiles at sea and carriers launching combat aircraft. It also shows repeated strikes on Iranian military targets. It said its forces are "delivering an overwhelming and unrelenting blow."

Iran's surviving leaders “want to talk, and I have agreed to talk," Trump told The Atlantic in a Sunday interview.
