Starting in 1945. WW2 wasn't what you think it was. The atom bomb triggered the ET races to come to earth to say "what the heck are you all doing?"
The military Industrial Complex never shut down after World War 2 probably as a result of fearing the ET's who came with big hearts (b/c men with small brains think small). The military industrial complex sucked money and energy from the Government and "we" ('they") allowed it, likely under all kinds of stress and pressure. In the 1960's people almost woke up until the Heavy Metal music was created in the late 1960's which in fact has been shown to be able to change DNA for the less better. That seems to have been driven by Private Prison owners among others.
Then came the Private Prison owners. Then came a series of movies to distort end times.
Then came modification of R and B into wrap that glorified Drugs and Money while a general push to separate races and generations.
Meanwhile. The media had gotten into News Making instead of News Reporting and as such, when something really news worthy needed to be covered they couldn't do it because they would get outed for faking news stories as far back as World War 2 for the Army. The major switch flip looks like it happened with the Post Apollo 11 news conference, however.
When we went into Iraq in the early 1990s the Europeans had seen enough. They started trying to kill the world with GMOs (and maybe rightfully so). Then came 9/11. If the Europeans (and Asians) weren't that concerned before that they sure were after that. What kind of country has a false flag from Mickey Mouse and doesn't get it investigated. From there it's been nothing but banking and media wars. I"ve left out a lot of details, but that's a general overview since 1945.
== Want to start in 1910? ==
If we expand out from there a bit the next best place to start is 1910's. The Big Banking families in the US couldn't agree on new banking in teh early 1900's so the Titanic was sunk wiping out the Aster family and a few others. The others left created the FED. But it wasn't just banking they went after. Their's was a full push to focus all commere and industry on chemicals. Donations were made to Medical Schools and then in return they asked to modify the curriculum. They suppressed food and natural solutions that weren't profited and trained docs to basically become sales reps for pharmaceuticals most of which are likely as much now sugar pills as anything else given the advertising in the US. They also went after all the railroads and swapped those out for black top roads and gas cars. Alcohol was banned b/c they didn't want people making their own fuel. Marijuanna was banned when the cotten-gin for Hemp was created and threated all the bankers investments in lumbers and timber. in the 1930's and 40's a full court press went on to suppress all Tesla Technology as well as all "Wellness" Technology.
I could expand out to the 1860's, or 1840's or late 1700s and I can keep going back through Greece to Summaria. From there it gets a little foggy but I could probably get further back if I didn't have to babysit.
Basically, we've been living in the dark ages since 1918 or so. But it sure looks modern!
