First of all, if you are going to make a conspiracy theory informative video, you should back your facts with resources. Every single thing that was stated was speculation. "the grey streak behind the militant figure represents some sort of poisonous gas," she said. Perhaps it is just part of the artistic composition? You could make ill-informed assumptions about any work of art. Doing so only makes you less credible.
Second of all, I am not going to take anything seriously from a native woman with 5th grade speaking skills.
The Swaztika - It is natural human pareidolic tendency to look for things like that, especially with people who are stupid enough to concoct conspiracy theories. Also, the Swaztika was originally from the Hindu and Buddhist religions, which represented love and mercy when facing left, and strength and intelligence when facing right. Lots of buildings are shaped like swastikas. Lots of buildings are shaped like dicks too; that doesn't mean there is some sort of royal sect that is trying to wipe out the world with a ginormous dick or something.
I've seen those paintings before and yes, they're creepy as shit. But to contrive something as absurd as an International Geneocide? That in itself shows how gullible these people are.
How do we even know those were legit pictures of the tunnels? They looked like screenshots from Jackie Chan's 1991 release, Armour of God II: Operation Condor. In fact, the entire underground theory seems to have been taken from that movie. Hmm...
