You're of course entitled to your opinion, and no doubt Iran sees things similarly.
Killing several IRGC officers in an Iranian military command post in Damascus is somewhat higher profile than other back and forth attacks by the two sides in their shadow war.
However, the Iranian terror attack that massacred 85 civilians in a Buenos Aires, Argentina Jewish community center in 1994 (https://www.nbcnews.com/news/latino/argentinas-highest-criminal-court-blames-iran-hezbollah-jewish-center-rcna147548) was far worse.
Firing a large barrage of missiles and explosive drones from Iran's territory into Israel is an entirely different kettle of fish, at least in Israel's eyes, as last night's retaliation strike by Israel proves.
Unfortunately, Israel picked a direct assault response, which I fear is likely to goad Iran into an even bigger attack than their last. If so, I fear that all out war is nearly inevitable.
