Thanks for your reply.Iran has retaliated against Israeli sabotage in many instances. However in the west they either outright deny or try to downplay such events. In some cases they can't hide certain occurences and that is when you hear about it.
If you recall the drone attacks on Israeli shipping. Also a few months ago there were several mysterious fires and explosions at various Israeli factories, installations,
In a recent interview General Hajizadeh of Iran hinted at such occurences merely stating that " we often hear about it" He also mentioned that recently a karge number of Israeli agents / spiess had been killed Iraq. Some call him the new Soleimani.
1.) Attacking economic interests of corporations belonging to a country (as is the case with the attack on shipping vessels) in response to a country directly targeting your defense/military minds and installations is not exactly tit-for-tat --- but at least Iran did something.
2.) Yes, I did hear about the sabotage at some Israeli sites.
3.) Deterrence will work when Israel is too afraid to assassinate a high ranking Iranian --- that is the litmus test.
4.) I believe those killed in Iraq were assets, not actual Mossad officers --- though I could be wrong
The good news is that Iran is actively engaged with this threat. It must find the sophisticated disinformation and propaganda war that aims to weaponize its own citizens against its government. This requires brilliant minds to gently show your youth the truth, rather than coercion.
