Iran did not achieve any kind of strategic victory. That's a delusional take.
They achieved a few tactical victories.
However, we know their air defenses were actually destroyed after TP2 as Israel claimed and their airspace is now open to Israeli attacks.
The only way this turns into a strategy victory is if they now actually weaponize their nuclear program and race to a nuclear weapon, and successfully test one.
A strategic victory isn't domination over the enemy.
Strategic victory merely means that you came out better than expected at the end of the war, and weren't defeated.
Iran's nuclear program has not been compromised in any form of negotiations.
Iran's command and control remains intact.
Iran's leadership has survived (an admittedly, very weak attempt at) a regime change attempt.
Their missile production remains in tact.
They managed to do considerable damage to Israel, and deplete their air defenses.
They managed to get to the end of the war in tact.
Its a strategic victory.
The Iranians didn't manage to gain the over all tactical edge throughout the war. While they managed to hit Israel and deplete their air defenses, Israel was doing a decent job of hunting down launchers and missiles bring transported.
Iran's missile inventory has likely depleted to a large extent through out this war.
Thus it was not an over all tactical victory for thr Iranians.
