We're going off on a tangent here.
The gist of the original debate being that Israel are bad for attacking the Iranian embassy in Damascus, whilst disregarding the fact than Iran are just as bad as they've also been involved in attacking other nations embassies.
The high court in Argentina only 2 days ago put the blame for the Israeli embassy bombing on Iran and declared it a terrorist state. Now they didn't come to that decision overnight - it took them decades of painstaking forensic work and sifting through intel to arrive at that decision - hopefully now the families of the victims can sue Iran through international courts for the loss of their loved ones.
There is a massive difference between being involved in an attack carried out by a third party on an embassy, a diplomat or the territory of another state and the military forces of a country carrying the attack out themselves.
The latter is unequivocally an act of war against the target state if that state wants to see it as such; the former only rarely is depending on the level of involvement. It should also be pointed out that the Argentina attacks didn’t take place in a vacuum; there were attacks on Israeli embassies and diplomats throughout the 1970s 80s and 90s (including two in London), not all of which involved Iran so there was a lot of plausible deniability (which the Israelis also used in their attacks within Iran and other places).
In short it is really rare for a state to openly and deliberately attack another countries embassy or consulates even in wartime. It was a considerable escalation carried out by the Israeli government and any state with the ability to respond to being attacked would have done so.
As I said earlier, such an act really should have been condemned by every state because it puts every diplomatic premises at great risk.
