Tell that to all the pon pon waving cheerleaders.
Thing is whatever businesses, manufacturing or facilities Iran is targeting in Arab countries, will only shift to Israel post war.
In essence Iran is creating further opportunities for Israel and making them stronger.
Likewise as Iran is making GCC countries a hostage, these countries won't turn into friends of Iran , and will only build harder defences against Iran.
Iran had little succes in hitting Israel. A little Mortar shell mounted on a missile here and there, doesn't count as a lot.
To compensate for that, Iran is making newer and closer enemies.
