Where is the actual OSINT though? No geolocation where the refueling is taking place, no timestamp on photo, no suggestion where the bomb is dropped.
By your logic an OSINT account can show a picture of a SU-34 in the air with 4 UMPK bombs, write "On its way to Odessa" and people will think Russia has air supremacy over Odessa.
Extraordinary claims require extraordinary evidence. We know that Russian air force is actively using gliding bombs to attack objects on the front line while flying over the territory controlled by Russia. One would need strong evidence to convince us that they have started to use gliding bombs differently.
The US on other hand is flying over the Iran for a month so the claim that they started to use B-52 in addition to smaller jets is not extraordinary. It would be strange to deploy B-52 with GBU only to strike something on/near the Iranian border (where there are not many targets which would justify GBU usage) so it's a logical conclusion from the posted photo that B-52 can fly over the Iran (at altitude beyond MANPADS reach).
