Attack major Israeli intelligence sites, long range SINIT/radar sites, Mossad headquarters, Ministry of defense, hit the hangers containing F-35.
And lastly a decapitation strike of an high ranking Israeli military official.
Anything short of the above is just not going to cut it.
Israel will continuing taking the important chess pieces off the board and Iran will be clapping when they finally manage a single pawn.
The only other country that has lost as much generals in war/conflict besides Iran has been syria (civil war) and Russia (Ukraine war).
Iran is in neither situation and losing high ranking officials every year for last 10 years.
I now firmly believe that Tehrani Moghdam was killed in a sabotage/projectile strike that ignited the base and set off a chain explosion way back in 2011.
