It is odd for the US defense secretary to be laying the groundwork for an event that could be organized by Tehran

Pete Hegseth’s plans to stage a public execution resemble a grotesque Iran-imitation game.

Having failed over the past seven months to defeat the Tehran regime on the battlefield, the self-styled “secretary of war” now proposes to mirror its notorious practice of enforcing the death penalty as a grand public spectacle.

Governor halts execution of William Lee Thompson, after Christa Pike survived failed lethal injections

Ron DeSantis cancelled a planned execution in the state on Friday, days before a 74-year-old man was due to be killed by lethal injection.

The move – the first time Florida’s governor has withdrawn a death warrant in his nearly eight years in office – comes just over a week after the botched execution of Christa Pike in Tennessee.

The US is facing worldwide condemnation over a “barbaric” plan to execute a disabled man by firing squad and livestream it to the public, with critics comparing the Trump administration to dictatorships in Iran and Afghanistan.

The Pentagon confirmed on Thursday that the execution of Nidal Malik Hasan, convicted of killing 13 people at a military base at Fort Hood in Texas in 2009, would be livestreamed on 3 December.

Livestreaming an execution could cause post-traumatic stress disorder in the viewing public, mental health experts have said, after the US confirmed plans to broadcast the death by firing squad of a man who shot dead 13 unarmed soldiers.

The US defence secretary, Pete Hegseth, said on Thursday that Nidal Hasan, a former army psychiatrist who killed 13 people at Fort Hood in 2009, would be executed by firing squad on 3 December. Officials later confirmed it would be livestreamed. It is believed it will be the first public execution in the US in almost a century.

Lethal injection was a way for us to deny the reality of capital punishment. Pike’s experience shows us what it is

Christa Pike had asked to be hanged. In the weeks before her botched execution by lethal injection on 30 September, in which she survived two lethal doses of barbiturate pentobarbital and had to be hospitalized, Pike and her legal team had challenged Tennessee’s execution protocol.

The state’s lethal injection regimen had failed before. In May, Tony Carruthers was also sent to Tennessee’s death chamber, only to leave alive after prison officials struggled to find a vein.

Pete Hegseth has said the execution of Nidal Hasan, the former army psychiatrist who killed 13 people at Fort Hood, will be a public event when the sentence is carried out later this year. A defence department official later confirmed the execution would be livestreamed. In an interview with the rightwing channel Real America’s Voice, the defence secretary said the firing squad would carry out the sentence at Fort Hood, Texas on 3 December. It would be the first US military execution in more than 60 years
