Iran has threatened to deploy a policy of "zero restraint" if the US makes good on its ultimatum to ‘obliterate’ Tehran’s power plants. The country also plans to target energy infrastructure across the Persian Gulf and banks that do business with the US. Iran's Parliament Speaker, Mohammad ⁠Baqher Qalibaf, warned of a mass retaliatory attack that would increase energy costs across the world. The Iranian military has warned that any attack on Tehran's power plants would result in the full closure of the Strait of Hormuz and attacks on energy and communications infrastructure linked to the US linked to Iran. Treasury Secretary Scott Bessent defended the president's stance, arguing that escalation could be the best way to de-escalate the conflict.
