It’s a Hell of a lot older than that.
The original globalist cabal was, of course, the Jews. They’re still the globalist cabal, but the smarter of the conspiracy theorists have learned that if you say “Jewish Conspiracy” in polite company, people begin to realize what you really are. It peels off the mask a bit, you see, and the toothbrush mustache becomes visible. Luckily, the Bolsheviks became the Soviets and were still Jews at heart, just like old Karl Marx was, so they could couch their hatred in terms of Anti-Communism. Communism’s internationalist bent just makes it even better: The Jews, who are all Communists, are using subversion to overthrow all national governments and implement One-Worldism and an Anti-Christian state, called a “New World Order” even back then. The John Birch Society, the Tea Party of the 1950s, fits in about here, but they weren’t alone.
The UN has been the first stage of the New World Order’s One World Government for as long as it’s existed. Even worse, many Presidents and other leaders, especially George H. W. Bush, have used the phrase “New World Order” to describe what they saw as big turning points in history. The fact GHWB was President during the end of the Cold War is utterly irrelevant because the dollar bill has a pyramid on it and they can mis-translate a tired Latin tag. (Novus Ordo Seclorum)
The whole New World Order thing is older than Bush the Elder, of course; it’s mentioned in the screed None Dare Call It Conspiracy (1971), probably the most hilariously misnamed book of the past four decades. However, the most modern form comes from GHWB’s time, because after the Cold War, the traditional enemy was gone so somewhat different versions of the old stories had to be invented. The right-wing conspiracy theory tropes most familiar to me, the black helicopters and FEMA concentration camps, for example, come from this period. The imminent confiscation of all firearms is older, but a hardy perennial watered from time to time with the gold of so-called patriots. Anyway, that’s when this crap was first articulated in its modern form; the stuff they’re throwing at Hillary Clinton now is essentially the same as what they threw at her and Bill Clinton when Bill was President. Obama was an unknown when this iteration of the insanity virus evolved.
The modern right-wing militias come from this era also, as do their terrorist actions. Abortion clinic bombings, the Oklahoma City bombing… the 1990s weren’t a carefree time. There was a serious up-tick in right-wing violence. Even if Trump causes a substantial increase in general fuckery, it would take quite a bit to get back to those levels. (And the 1990s weren’t a patch on the 1920s, when the reformed KKK ran rampant with no effective governmental response… )
Ultimately, for all that this insanity’s changed, it’s all the same stuff underneath. It’s still rampant xenophobia, still antisemitism in a thin mask, still jumping at shadows. The Sovereign Citizen movement is a close cousin to all of this, and it heartens me to see law enforcement taking it seriously. It gives us a chance to avoid or short-circuit another rise of this kind of violence.
