In context of this session, I've been mulling over how I would pull off an invasion if I were some 4D STS empire. What I came up with is that I would assure the US-based Consortium that they were my "chosen people" to carry out my plans of creating a utopia on Earth and that other people such as Putin and his sympathizers were impediments to the creation of the perfect world. I would then goad the US into a war it cannot win, blinded by my assurances that I will leverage my technology to make it impossible for them to lose. When the US is backed into a corner and faced with certain defeat, I would use my thought altering technology to amplify the fear and desperation of the US establishment to the point that they will take "if we can't have it no one will" to its ultimate conclusion and launch every nuclear weapon they've got, forcing Russia to respond in kind. On the brink of nuclear destruction, I would then take one of my shiny transdimensional space cruisers and very ostentatiously disable all of the missles, since it is such a trivial matter, and disappear into a flash of light. At the conclusion of this spectacle, I would leave behind instructions, which could be broadcast and received by all humans, on how to create a perfect world, along with an implicit warning that if the poor ignorant humans screw up again, I won't be around to save them next time. I would conclude the message with the promise that if the humans successfully implement my reforms, they will be welcomed into a greater galactic community where we can all be friends in eternal bliss. The instructions would contain schematics for such things as free energy technology, medbeds that could cure any ailment, psychotronic communication devices, as well as a multitude of Trojan horses which ensures humanity becomes dependent on infrastructure I control, and can be weaponized at my whim.
From there, there would be no further direct interventions in humanity's reality until the culmination of the plan; I would just sit back and watch them dig their own graves. Awed by my sudden and unpredictable intervention in an extinction I secretly helped to instigate, and wondered by my mysterious appearance and equally mysterious disappearance, they would be overwhelmed by curiosity and a sense of gratitude that most would unquestionably take up the agenda in order to balance the sense of debt and finally be harmonized in the coming promised paradise. The old elite would be deposed and replaced by "visionaries" like Musk, who would likely be all too willing to exert their freewill and that of countless others building the fantastic new technologies that I would later use to impose a control system. There would be the issue of people who knew what the plan was all along, as well as pawns who have outlived their usefulness to be disposed of, which would be addressed with the existing policy of covert abductions and targeted special-forces types of activities. After that, it is only a matter of waiting until the ground is sufficiently prepared for my grand debut and then simply flipping the switch at the opportune moment.
