I think Many Worlds is important to understanding this; At a higher level of reality than 4D, all possible outcomes occur. In order for the STS agenda to succeed, the people must choose enslavement. It can be coerced, influenced, or even temporarily forced, but it must, in the end, be chosen. Ultimately, the end game is for humanity to worship 4D STS, in whatever physical form it may finally manifest, as the salvation and divine authority which will lead to nirvana. 4D STS cannot choose for a collective of hundreds of millions of humans without losing a great deal of energy. A study of 3D dictatorships reveals this. The "supreme leader" may start out with incredible power, but once people cease to be persuaded by him and lose more and more confidence, he must expend more and more of his own energy to compensate and keep people subdued with fear and violence. This often leads to a feedback loop, where the more he abridges their freewill, the quicker people turn against him, which causes him to resort to even more brutal methods, which accelerates the process even more, until the "almighty leader" suddenly runs out of energy and is then quickly overthrown in a dramatic coup. 4D STS has learned this lesson well, and that's why they won't do an Independence Day style invasion.
So, the mass consciousness chooses the timeline it wants to experience, and while the Lizzies can meddle with it, they can't completely override it. So perhaps they think Trump is a problem and they want to get rid of him. I don't think this is actually the case, which I'll get to in a moment, but we will start with this assumption. They go back to 2015 and beam him with some type of death ray and he has a heart attack and dies. The people who really hate him, such as the snowflake movement, may be really asking for that reality and so the Lizzies may be able to capture their "loosh" by getting them to resonate to that particular timeline and move into it. On the other hand, there is a large group of people who do want to experience the Trump reality and will never rest until they see it. These people will not accept the Lizzies' new timeline unless forced, and bringing that energy down to 3D to force that many people is way too costly. I believe that since time is simultaneous and not linear, the people who are so happy right now that Trump got elected emanate impressions which can reach across the spacetime and influence themselves when they were striving and yearning for Trump to get elected. Therefore, with this understanding, the future can affect the past which creates the present. In fact, this basic premise provides the basic theoretical framework for understanding how the Cassiopaean transmissions are possible. For all intents and purposes, on the timeline that we are currently on, it looks pretty much impossible that we could ever evolve into anything remotely resembling the Cassiopaeans. And yet they say this occurred, and they are broadcasting energy from the future into the past which changes our present timeline in a sort of stairstep fashion.
So we have people who move into the Hillary reality and the Trump reality. A proponent of linear time would say this creates a paradox, but the universe has room for all possibilities to maximize the richness of the grand experiment. So what actually happens is that the reality splits. On our timeline, the people wanting the Hillary reality, move into that timeline, and on our timeline they either fade into obscurity or become like zombies because their soul energy has basically left this particular branch of reality. So even if the Lizzies killed Trump, it would only be experienced by the people they could persuade, or were willing to force (basically by broadcasting thought projections that he could never win, so there was no point and making it something of a self-fulfilling prophecy), to accept that timeline. In order to fully destroy a timeline, they have to make it so that it has no observers. So they will try to engineer these splitting events to get as many people as possible corralled into a timeline that they like, perhaps only resorting to physical violence as a mop-up operation to eliminate a few stragglers who might be causing problems. Of course the stragglers will then most likely reincarnate on a different planet that is more strongly polarized towards STO, and will be an even bigger headache later on in their bid for total control of 1-4D. All of that would depend on if the risk of a distant war with some other more strongly polarized planetary base is worth the reward of cementing control over Earth now and adding another world to the Orion Empire. So the game is extremely vast. In order to secure complete control of the planet, they would have to remove all STO observers from decillions of possible timelines for all of eternity. While they may dream of this, I believe they will have to accept partial victories at their present level of power.
The second question is does Trump really matter that much? I don't believe that he does, as long as in the long run it allows the Orion group to capture more and more timelines in their bid for complete control. Perhaps a businessman is just what they need; some of Trump's ostensibly positive ideas could be twisted to support the business of cosmic conquest. Maybe humanity needs an economic revitalization so that it can cheerfully build the infrastructure that is required for the "invasion" to take place. Since much of our modern technology is based on reverse engineered Roswell tech, the integration should be seamless. Furthermore, everything will be viewed as a resource, ores and minerals, plants and animals, and human beings, and how to allocate them efficiently will be the most esteemed science. While this may lead to a more equitable society with less waste, the single minded focus on business efficiency will not encourage any sort of personal or spiritual growth on its own. The American business ethos (before it was twisted by neoliberalism) may be good for growing an economy, as long as it is somewhat mediated with common-sense regulations, however there is danger if it is placed on a pedestal as the divine archetype which rules all of human life. Taken to its ultimate manifestation, the machine-like efficiency and preoccupation with economizing energy to undercut the competition and become the biggest and best corporation in existence is not so much different than Dr. Jacobs musings about the guiding philosophy of the extraterrestrial society which he has ascertained from abductee data. Maybe, in his own way, he's preparing the ground for acceptance of that society. I'm sure that's not quite the vision that Trump intends, but there is good and evil and the specific situation which determines which is which. For two concurrent situations, what is evil in one of them may be good in the other. Does Trump understand the Law of Three? Does he understand that the Earth is a school and people incarnate here to have certain experiences which contribute to their spiritual growth, and for all he knows about business, it is only a means to that end? Does he understand that in its current state, everything humanity does or accomplishes is "food for the moon?" I don't think he poses enough of a threat to the hyperdimensional control system for 4D STS to be too concerned about him. I don't think he understands how he can be used, despite having the best of intentions. So if the mass consciousness wants to take a slightly different route, the Lizzies will go with it and attempt to subtly incorporate it into their planned endgame. Until these concepts and more are part of the mainstream political discourse, I think any leader you get will at best be a flash in the pan as far as being able to facilitate positive evolution for humanity because they don't have a wide enough view to effectively deal with the reality of the human condition.
). So 4d does not equal all-powerful.
