Iran has reorganized its military to be more aggressive abroad as talks on ending the war with the U.S. remain mired in stalemate, a sign that Tehran is preparing for a protracted era of regional conflict.

A raft of top military appointments by Supreme Leader Mojtaba Khamenei marks a shift to an “offensive doctrine,” Mohammad Reza Naqdi, a general in the Islamic Revolutionary Guard Corps who advises the force’s new commander, said in an interview on state TV late Tuesday.

“Whenever the conditions are favorable and the order is issued, we must be able to take the operation into enemy territory,” he said, contrasting the approach with a prewar doctrine that was “primarily based on defense and the preservation of the country.”
