Totally agree, and I think you nailed it. He has covered the 'basic consipracy theories' quite formidably but, as you say, he appears to have limits in 'where' he can go. I don't hold that against him but during the past year I've just lost the appetite to listen to him, this stance of "Putin is just equally bad" being the final nail in the coffin. What it comes to, I think, is the classic balance between knowledge and being. I come to think of, for instance, sheikh Imran Hosein as an example where there's both knowledge and (a lot of) being. I get the sense that one gets more quickly tired and 'bored' listening to talks where there's less being.I'm highly skeptical of Corbett. To him, everyone in a position of power is automatically a "bad guy" who's in on the globalist agenda in some way. It's a naive, simplistic way to view the situation. He does get a lot of stuff right, but I think he's got cognitive limits that don't allow him to take his analyses past a certain level of nuance. Seems like a bit of a "gatekeeper" for the conspiracy crowd.
I've been playing with these ideas in my head and tried to think of 'practical' examples. One thing I came to think of is that if there's an 'underground civilization' with secret tech that is centuries/millenia ahead of ours then you could suppose that any kind of weapons based on this tech is based on completely different concepts. We're not talking about e.g. machine guns or missiles that are superior/better (advanced versions of 'normal' tech) but weapons based on completely unheard-of solutions regarding what energy they use and how they operate. An 'alien' weapon would, presumably, not use any kind of bullets or projectiles. Instead, and I'm just guessing (LOL!), it would be some kind of 'energy weapon' that would just vaporize the enemy.Regarding "secret tech", if we consider the possibility of an entire advanced underground civilization, then it seems that controlling the awareness of humanity is the real name of the game otherwise they could just enhance the surface infrastructure to any desired level. It might be that the higher-level STS forces only wish the more advanced technologies to be available once the public has been sufficiently indoctrinated in materialism, atheism, or other restrictive modes of left-brain thought (and no doubt suitably depopulated).
Playing further with these ideas, I tried to imagine how this would apply to wars of the past. Let's take the Napoleonic wars for instance: during that time wars were fought mainly with cavalry and rifles (correct me if I'm wrong). If during these battles someone would have used Kalibr missiles that would surely have been seen as 'alien technology'. That would've raised questions like "how can that thing fly?", "where does it get its energy from?" and "what the hell makes that thing explode so massively?" Just guessing, but that would then cause a 'quantum leap' in technology for the masses. As historians have pointed out, once the US exploded its first atomic bomb the Russians, although not yeat having similar technology, knew that building and using one was possible.
Applying the above to the war in Ukraine, imagine if some kind of 'ray guns' using 'zero-point energy' were introduced to the battle field. Or stealth/invisible UFO:S that would just vaporize the troops. That could open a Pandora's box, for sure.
What you wrote got me thinking of the Nazi era and how they apparently tried to come up with the technology/science for nuclear weapons. If we suppose that they were channeling with the STS forces (Thule society etc.), and got some of their ideas (time machine?) from those forces, why didn't the STS/Orion dudes tell them how to build an atomic bomb? I sure as **** don't have an answer to this but I can think that in this instance the STO forces might have intervened in some way, causing the Nazis to opt for the development V2 rockets instead. In any case, someone decided to 'pull the plug' on the Nazi world domination project.And then there's the influence of 4D STO, who are likely helping out where Free Will allows. So imo, it's most likely that Russia has developed its own protective technologies, but like many technologies used in war, won't be declassified for years or unless other circumstances permit. The psychopathic elites could be trying to implement more advanced technologies to get around this, but the population might be insufficiently "prepared" at this point, leaving the elites open to the "risk" of creating an explosion of awareness if they deploy such technologies without due caution.
