Donald Trump told NBC the strikes were ordered because Iran would not commit to halting nuclear research and that its growing ballistic program posed a ‘‘colossal’’ threat. He warned that Iran must not retaliate or it would face unprecedented force, a message he also shared on social media.
Officials confirmed at least four U.S. service members were killed and others wounded in the recent attacks. Trump acknowledged more American casualties are possible as the campaign continues, offering condolences to the families of the fallen.
