There were several countries arguably interested in getting rid of that pipeline (Ukraine, Poland, the US), but Ukraine wanted it the most, had easy access, and there's no need to overcomplicate internet theories.
No, "normal" humans don't dive to 80m deep, where the explosion occurred. Any diver, whether professional or recreational (which is my case), will know about this. I don't have a (alternative) theory about this, I'm just stating facts. Well, the alternative theory, if we are speaking of divers, is that they had some very special equipment and were extremely skilled. It wasn't some random people, renting a random boat, renting random diving gear and buying random explosives ..

This simply isn't true, I myself after a technical advancement in my PADI to be certified on a rebreather went >80m many times. It's absolute more common than it was in the past.
Those who are trained with special forces as alleged would also be required to be qualified.
My main point is that it's not as rare as some might think, it's becoming more and more recreational.
The people who did it definitely took on risk, but in my eyes, more so because if something did happen to go wrong, there's no support to help you out (that we know of). It's a flying with 1 engine scenario. The fact that it was pulled off is impressive. But for any rec divers, don't try without the right training, equipment and people with you.
"The open-sea diving depth record was achieved in 1988 by a team of COMEX and French Navy divers who performed pipeline connection exercises at a depth of 534 metres (1,750 ft) in the Mediterranean Sea as part of the "Hydra 8" programme employing heliox and hydrox."
Sounds like 80 meters is cake walk for any modern naval institution.
Not trying to give any hints there, just sharing some rummors.
>Advanced Mixed Gas Diver (80m)...The Advanced Mixed Gas Diver course is a great way to extend already considerable open-circuit mixed gas diving skills.
Yes, it's an operation that requires coordination and planning, which is why it's reasonable to assume it was carried out by an intelligence agency and not a lone fisherman with a grudge. But once you're in the realm of intelligence activities, this isn't exactly the "let's blow up their pagers" level of complexity.
Bringing that bridge down is also much harder than blowing up the pipeline, because the bridge is covered by a lot of defenses, and naval drones will always have limited payload (if they want to be fast enough to evade defenses). Dudes performing a dive in the middle of the sea far from the battlefield are much less vulnerable.
