There is one force that controls what major things happen in the government.
Which COVID policies are enacted.
How open the border is.
The future demographics of the country.
Which wars we support or fight in.
Which truths are allowed to be told.
Who is allowed to be elected to the Presidency.
Whether the President will be spied on or not.
Whether the President will be killed or not.
What the Federal Reserve policies will be.
etc...
Certainly there is some room for politics and partisan wrangling when it comes to unimportant issues like social issues and dividing up the spoils of the American corpse amongst themselves.
But on the important issues, there is one entity calling the shots.
But on the issue of UFOs, the DOD is comprised of many different factions, some of whom want disclosure, some who deny the issue exists, and some who are determined to hide the issue behind NDAs and stigmas (and worse).
Even within the various service branches, opinions differ re: UFOs.
The Air Force refuses to even discuss the matter and has refused access to their files to members of Congressional committees that have legal oversight powers. The Navy on the other hand has been increasingly forthcoming on the issue, admitting that there's something there that we can't identify and don't understand.
