I will give a few brief statements for understanding.
Negativity did not exist in ET experience until humans were involved. Think hard about that.
Thought processes between ET and human are extremely different. They do not understand deception/lies/falsities. ETs experienced that when certain treaties were broken and dissolved. They do not live reality in accordance to the fantasy element like humans do. They live according to true knowledge of universal truths. Humans live according to lies/deception that accrued throughout human history.
An example of this, OP, is if you were to have an ET experience, and you behaving as if they were an element of the Illumanati, when in fact, they are their own beings. DECEPTION is not involved in their own condition. Humans bring the DECEPTION into the mix to confuse the ET issue.
They are as advanced in spiritual aspects of being, as they are in technology. Many, if not all, of their technologies are based on consciousness. These techs WILL NOT WORK PROPERLY if consciousness is acting on deceptions/lies and fantasies. TPTB cannot figure that out...and only recently is that beginning to become known. This put TPTB in a bad situation, because unless they change their thought patterns, they cannot control or back engineer and use the tech to its fullest extent. There is a process in place to turn the pyramid upside down.
The military complex is clueless and has NO control over ANY of the ET condition. That is why you still see helicopters and jets scrambling and 'chasing' UFOs.
When ETs discovered the thought patterns and deception of our leaders, it set out to make contact through the 'normal' populace. This makes the contact and disclosure process much longer, and much more delicate. The ETs hadn't realized exactly how far we have traveled away from 'Home'.
Last thing I will say, is that Disclosure is NOT going to occur through politicians and diplomats. It is still undecided if there will actually be a full disclosure (it depends on what happens to the human condition during the next year and a half), but if disclosure is to occur, it will be the ETs choice and decision...no one elses.
