Mmm...

First thought, and admittedly half baked and very Neil Breen-ish but I just wanted to play along: maybe go semi-Ozymandias and invest in the largest PMC ever, having even aircraft carriers and ICBMs, backed by technological giants like Microsoft and Space X, but chip them all with some sort of kill switch (that immediately explodes if you try taking it out), and slowly but surely destroy Western/imperialistic military forces around the world, starting with their involvement in the global South. They'd be extremely well compensated, so the mercenaries from opposing militaries would join too. Eventually, take this force to the mainland and, after giving them a period of grace for them to come clean and accept their incarceration/fines willingly, take out all the bankers, corrupt politicians, immoral heads of businesses and shareholders, etc etc (including, of course, Microsoft and SpaceX, lol). The police force, stupid defenders of our slavers, would also be given a warning and asked to stay home or join, before getting rolled over by the chipped PMC. After the military forces of the enemies of humanity are depleted, and the people once again feel like they have their destinies in their hands, establish a new era of unironic God-fearing commie love and peace, without the moral relativism, consumerism and hedonism of yesterday. And, foundationally for these new societies, abolish interest. Finally, move this PMC to some remote island and establish a community there (PTSD is a bitch and I don't want veterans going "First Blood" everywhere), one that is materially comfortable and allows them to have some semblance of normality after shedding so much blood (necessary, but still traumatizing).

Second idea: buy all media and news companies and change their entire modus operandi by reporting only facts, with narratives based on morality, and flood minds with the right ideas (Solomonic post-nihilism [seriously, read Ecclesiastes], Jesus' love for others instead of self, Qur'anic verses, but also the forgotten Western wisdoms like Socratic and Humian epistemology, Kantian morality, Wittgenstein... to ease those who have been hurt/disappointed by organized religion and are beasts of propaganda and entertainment into good thoughts [you can't just go 0-100 the same way an alcoholic cannot go from a daily bottle of vodka to nothing]).

I think my second idea is better but I feel I'd just get taken out before making any major change, lol.
