If I try to step back and look at the bigger picture, 40,000ft view. I can confidently say that Q is a psychological operation conducted by military and/or government officials with high clearance that Trump is aware of and has not renounced. It would also seem that Scavino is also somewhat involved based on posts and their timing.
As to the purpose, I would say it is to sway public opinion and provide some sort of direction for those seeking answers and truth. To give clues into the corruption that plagues the current governments of the world, especially the US. To what end, I do not know. My opinion is that the country needs something to unite it again, somewhat like the events of 9/11 united us. That leads me to believe that we all have to experience some kind of massive national/worldwide trauma or difficult period together where everyone feels it, to the extent that political alliance and divisive issues seem meaningless in comparison. Looking for opinions, I want to believe that Covid was that necessary event but people are still far from united. Do you think the eventual revelations of vaccine damages and the intentional release of the virus will be enough or are we still in for another period of some new pandemic/war before the dawn?
Every single country submitted to Trump. The militaries of the world have been plotting this since WW2 (the closest we got to overthrowing central banking).
Why do you think there are things more secretive than POTUS can see?
Why is POTUS so somber in so many pictures? He knows what the truth is.
I tend to differ slightly in the origin: I believe, from history, that the actual beginning of Q (not by that name: that's much more recent) was after the sinking of "Titanic", when Astor and others were eliminated as cabal opposition. Those who remained knew they couldn't defeat the cabal then, and it would take time and organization. Since then, when they were able, they threw wrenches into the gears of the cabal, such as Adolf and Operation Barbarossa to stop Stalin's military from subjugating all of Europe.
I doubt Trump knows of all the resources available to him. He obviously doesn't know the intricacies of what SpecOps does, nor of their capabilities. Few people do, outside those groups. Trump has a general idea, but there are things hidden from everyone except those involved. It has to be that way. Q stated that there are technologies not available to the public: some of those aren't available to the CiC either, at least not until "conspiracy theorists" and such make their discoveries. It is unfortunate, in a way, that the military can so effectively hide their stuff, but I guarantee they can. That is something I have personally experienced, during and after Vietnam.
Trump is somber because he knows that much of the collateral damage is necessary; he also knows, to some extent, what the cocksuckers (forgive, please, it's just my emotional side coming out) have done to humanity. I know also how that is: there was a time in my life I was known as "Old Stoneface", because it's damned hard to ignore that which one has seen and experienced.
