Yes, a History Lesson.

Very good article. Very long article. Worth the read.

The name of this article is:
POLITICAL MANAGEMENT
OF THE EXTRATERRESTRIAL PRESENCE:
THE CHALLENGE TO DEMOCRACY AND LIBERTY IN AMERICA

Link: http://www.exopolitics.org/Study-Paper-5.htm

Excerpt:
Political management of the extraterrestrial (ET) presence on Earth has evolved during the course of the successive US Presidential administrations that had to deal with the policy issues that arose once irrefutable proof of such a presence was brought to the attention of policy makers. This evolution of responses by Presidential administrations can be broken into five historic phases which demonstrate a gradual erosion of Presidential/executive oversight, and the growing autonomy/independence of clandestine organizations embedded in military-intelligence and national security branches of government. This erosion of Presidential/executive oversight in the form of ultimate control of the ET presence being gradually taken away from elected Presidents and/or their congressionally approved political appointments appears to have all the characteristics of a 'political coup'. Presidents, in the case of Republicans, have been reduced to rubber stamps for those controlling political management of ET issues; or, in the case of Democratic Presidents, to political irrelevance.
In this paper, I will identify the political management approach taken in the various phases of how US administrations/clandestine organizations have responded to the ET presence. I will analyse the gradual erosion of executive oversight of these clandestine organizations, and the latter's increasing influence over the executive branch of government. I will also outline the increased role of Corporate America and the Council of Foreign Relations in politically managing the ET presence. I further examine the most current political management style as evidenced by the US led military intervention into Iraq and what this suggests for how the ET presence will be managed in the future. I conclude by identifying how political management of the ET presence has been conducted in a way that represents a threat to the principles of democracy and liberty in the US.

This is a fantastic website in my opinion.
Many articles to read.  
Check it out.  Worth it.  Makes sense to me after 'adding it all up'.

So when people will say or think that the President has 'Security Clearance' for anything and everything then 'Think Again'. :)
He most definitely does not...

The paper has much of what I have read elsewhere. Then as now I find myself in various mindsets on the issue.

It's a little difficult to think that such a large number of people as suggested here are all going to be hush-hush about something so powerfully relevant to the whole of society. There have been 'whistleblowers' but somehow they've been swept under the rug or if the implications are correct, swept six feet under. It would also mean that considering how much time has passed it is not only a few MJ'ers here or whatever other group there, what it looks like is that an entire culture of people have developed this along generations. The 40-year old military person who may now be in some capacity involved with all of this is not someone who was around in 1947 or earlier. One can only imagine a father-son discussion where Dad tells Junior how really different they are from the rest of the world's populace.  

Another very puzzling piece to all of this is why would an advanced ET race subject themselves to signing a treaty with earthly, clandestine organizations or any negotiations for that matter? One would figure that such a race(s) would already know much about the Earth, its inhabitants and their psychological standing. If they were evil and advanced, such as has been implied for the Orion group in this paper and elsewhere, then what's stopping them from an all-out takeover? I can't say for certain but something seems off in that equation.

Another possibility is one that may in fact have nothing to do with aliens at all. It makes think of large-scale disinformation, a situation where perhaps the finger should be looked at regardless of any moon it's pointing to.

But whichever way you cut it, it does make for a strange scenario and unfortunately a revelation as to government, truth and the influence of a few whether they wear Florsheims or anti-gravity boots.
