The Secret of Trump and Schwarzenegger
Germans use germs for weapons. That means self-defense has to include defending against microscopic threats and microscopic weapon. It also means defending against invisible radio waves and other forms of invisible and radioactive contamination. What they show you looks normal. What they don't show is the knife they hid behind their back.
Before I was born, Trump and Schwarzenegger(Donald + Arnold = Darn Old/Austria-Germany) had a bunch of office buildings constructed in Orange County. These office buildings would have surveillance in it, some would have speakers that would play creepy sounds, and some would have rooms that would drug the air. After that, Trump and Schwarzenegger invited a bunch of foreigners over to work in these office buildings. The new employees would slowly get drugged without their awareness, framed and blackmailed one by one after they came here to work. The foreigners couldn't say anything because they had accepted the blackmail so they wouldn't be killed or so their children wouldn't be hurt.
The Trump and Schwarzenegger alliance would first have their target secretly drugged without their awareness, then send an undercover to subliminally trigger the target, and have a police officer there to arrest the target if the drugs cause them to overreact. Once their target is in prison, it is easier for them to threaten and blackmail their target, secretly.
