Deliberate use of fear and propaganda as psychological weapons. It's the ultimate battered women's syndrome except, it's all sexes and ages of people. Global Warming/Climate Change, Covid19, 20, 21, Orange Man Bad, etc. Those are the ones that come to mind first, I'm sure there are many other examples. It will take some time for most to recover, some never will. My GF of 12 years is a survivor of 20+ years of abuse and she still occasionally falls into that mode.
