Parts of the wall are blown out,not the entire wall - considering Iranian(!) reports how many other people were in the same building and did not end up getting killed that is incredible precision like. Have you seen the damage a hellfire, a Popeye or a ROCKS missile does? They would only leave rubble of the building if fully armed and even when unarmed would harm far more people/cause more damage if only partially or unarmed. (And leave a lot of parts for the Iranian government to show around).

Besides: When Israel attacked Natanz they had to blast two more radar sites (Iraqi and Syrian) on their way. Nothing like that happened this time,even though both sides are operational again according to their respective militaries.

So there is definitely no air to surface missile involved here,sorry.

And while an attack with a purely ballistic missile is always possible basically everyone and their mother would detect these (including a lot of not very Israel friendly countries like Russia, Türkiye, Chins,etc.).

And in terms of a small drone: Sorry,but are you fucking kidding me? Hezbollah has the fucking Israeli border right in front of their door. A household DJI drone can fly from Hezbollah positions into Israel.

In the Iranian matter we have 600+km of Iranian(!) airspace just to get to the closest border towards Israel and over 1400km in total. You know what makes small drones small? Their small batteries and their small range. For a drone this large we are talking about the size of a Harop or larger - which would be very very observable on radar. And we haven't even talked about the second problem so far: Communication. A drone needs either a radio link to or very very EW resistant navigation. Neither the US,UK, France or Germany have pulled this off in a non stealth/much larger drone so far beyond a few hundreds km for an attack drone . And no, satellite connections are not a solution here as you can easily identify them with capable EW/AD operators (which Iran generally has + their neighbours definitely have). That's why global hawks, etc. are very much visible.

So unless Israel has a magic mini drone that flies 1400km undetected and without any good communication link for at least 700km there is only one option for the small drone scenario: That the Mossad/IDF managed to get some operators within 50km of Teheran, launch a previously unknown stealth drone unseen by local security agencies and AD, set up a very capable comm link without being picked up or aim the drone themselves and then exfil without being seen. Which is even a larger intelligence blunder than the bomb being placed inside the building.

So no,there is literally close to zero probability that the Israelis pulled off a missile or drone strike like that.

If they do have a magic drone that defies current technical limitations and a lot of physics the international community should be really worried and I must tip my head to them for such an extraordinary achievement.

And sorry, if you repeat the same sentence without any valid arguments it makes me wonder if you are just a shill spreading propaganda here. Oh wait. Let's have a look at your account. And oh wonder: You are exclusivly posting one sided content on the issue, often riddled with fake news.

You are indeed an IIR shill
