You are talking about 2 different things, one is Iran and its arsenal and usage of it, the second is the assassinations, unfortunately politics doesn't work like that in real lifethe deterrence is joke , because some guys in upper echelon are afraid of using it and are only talks .
you can have 14000km weapons but if you are afraid of using it , its useless as deterrence and right now our weapons are like that . Israel kill our commanders left and right and we are careful not to make any body nose bleed when we answer or we don't answer at all
only a useless joke of commander go and make threat about a new equation but about action ............
Iran proven its weapons are as advertised, 1450km shown in real combat inside Israel, same for S-136 and that's it everything has been proven, Iran is the only country in the world to have struck Israel and the US out of retaliation. A few years ago, those weapons were dubbed as "photoshopped plastic" or "30km CEP Saddam scuds"
This is something different than the assassinations, Iran has been like that but it's certain it has deterred Israel from doing crazy things like sinking Besshad or blowing up a consulate. Sinking Besshad for probably the next one if Iran didn't retaliated, also Iran should aim at all the countries using its Air Defense to shut down drones and missiles meant for Israel, this is what i hope the most if there is again a need to pummel Israel if they do something crazy
Now back to the real life, no, Iran will not pummel Israel for an advisor killed, if anyone thinks it works like that thank god none of them takes any decisions for Iran, 13th April was clearly aimed at deterring them to do crazy things such as sinking Besshad or aiming consulates
Meanwhile IDF troops, Staff Sergeant, officers are getting killed every day with all the weapons used from Iran (chosen race soldiers)
