It seems that the death of Khamenei has indeed triggered Iran to launch a holy war of revenge, suppressing the internal moderates. Up to now, it appears they have given up on illusions, fighting fiercely, accurately, and persistently. If they had fought like this before last year, maybe this situation wouldn't have arisen this year. In an era where offense is high and defense is low, systems like THAAD are useless. Ultimately, warfare comes down to both sides competing in industrial capacity and endurance. Russia and Ukraine are a typical example.
