well the Neo Nazis believe its real and they are getting armed to start a race war and take down Z.O.G
if you watch Gangland Season 5: Klan of Killers you will see they are talking about Z.O.G and the government warned the public that supremacist gangs are getting strength and increased recruitment by 54% this year because of immigration and Obama
Gangland is a fictional show, nothing on it is real. If that's where the ZOG is from, then here's your definitive answer. ZOG is 100% fake and made up.
I think it says in the first line of the article [Wiki] that it's fake...I don't know, Wikipedia likes to use complex word compounds that will probably never ever be seen again.....
So that would mean it's like Dharma and Umbrella I guess.
This is simply a term that anti-Semites use to claim that a country is actually run by Jewish people. The Wiki article says the term first emerged in the 70s, although this sort of thinking has been around since at least the 40s. Anyway, the term is completely made up and the concept is entirely untrue. It's a result of racism and ignorance.
