In 1947 at Fort MacArthur, in Northern California, began planned training of special reserve units.  What would become an obvious United Nations - U.S. plan in 1951. By 1951 there were several other such training programs on other military bases. July 31, 1951, the first simulated UN forces invasion and seizure of nine California cities: Compton, Culver City, Inglewood, Hawthorne, Huntington Park, Long Beach, Redondo Beach, South Gate and Torrance. Troops claiming the authority of the United Nations seized control of the infrastructure of these cities, arrested the mayors, law enforcement officers and all primary leaders of these communities.  The commanders of the troops issued manifestoes reading “by virtue of the authority vested in me by the United Nations Security Council.” At Huntington Park they held a flag-raising ceremony, taking down the American flag and running up in its place the United Nations banner.
The invasions were tactical strikes with full armored and air support. commanders of the troops issued manifestoes reading “by virtue of the authority vested in me by the United Nations Security Council. The populations of these communities were terrified and the troops behaved as fascist shock troops. The people of these communities had no way of knowing that it was a simulated drill until the exercise was ended. Can you imagine American troops willfully imposing such horror on their countrymen? Well, it wasn't imaginary. It happened and was reported in newspapers throughout America with pictures showing city officials in jail without any major outrage apparently.
On April 3, 1952, units claiming UN authority did the same thing at Lampasas, Texas. They took over the town, closed churches, strutted their authority over the teachers and posted guards in classrooms, set up concentration camps, and interned businessmen after holding brief kangaroo trials.
    In Texas things nearly got out of hand whet UN troopers forgot that it was simulation, when a highschool student refused to obey an order. "Ain’t nobody going to make me get up," cried John Snell, 17, his face beet-red. One of the paratroopers shoved the butt of his rifle within inches of Snell’s face and snarled, ‘You want this butt placed in your teeth? Get up.’”
The UN forces put up posters listing many offenses for which townspeople would be punished, including “Publishing or circulating or having in his possession with intent to publish or circulate, any printed or written matter ... hostile, detrimental, or disrespectful ... to the Government of any other of the United Nations.”
The American soldiers apparently gave no thought to their oath to protect and defend the United States Constitution, which all of our military and officials are sworn to defend. Why is it so easy for Americans to forget their duties and responsibilities to their own people?
August 20, 1952, Watertown, NY is siezed by forces flying the flag of the United Nations. The invasion was a full scale paratrooper, armored divisions invasion like the others with commanders claiming, "By virtue of the authority vested in me by the United Nations Security Council.”

Was/is this not outright high treason by any definition?

In February 1961, President Kennedy had Secretary of State Dean Rusk commission the so-called private Defense analyses [No. SCC 28270] to design a plan which would lead to global one world government. March 10, 1962 the Institute published Study Memorandum No. 7 written by Lincoln P. Bloomfield [CFR], A World Effectively Controlled By The United Nations.
September 1961, the President of the United States signs Department of State Publication 7277 to incremental transfer of American military forces and all weapons to UN command, calling for the total disarmiment of civilians in US and other countries. To end any challenge of UN authority. This plan was a policy first intiated by the Eisenhower Administration by then Secretary of State Christian Herter [CFR]  7277 is the blueprint leading to global one world governmment. Simply put it is proof of the Establishment elites intent to surrender America to an omnipotent United Nations.
 Was/is this not outright high treason by any definition?

Dr Bloomfield evidently thought that only those involved in the globalist movement would see the memorandum, because it's intent is plainly stated in the opening SUMMARY:
   " A world effectively controlled by the United Nations is one in which 'world government' would come about through the establishment of supranational institutions, characterized by mandatory universal membership and some ability to employ physical force. Effective control would thus entail a preponderance of political power in the hands of a supranational organization.... [T]he present UN Charter could theoretically be revised in order to erect such an organization equal to the task envisaged, thereby codifying a radical rearrangement of power in the world."
“...some ability to employ physical force” is clearer in the text of the document:
    "The principal features of a model system would include the following: (1) powers sufficient to monitor and enforce disarmament, settle disputes, and keep the peace - including taxing powers - with all other powers reserved to the nations; (2) an international force, balanced appropriately among ground, sea, air, and space elements, consisting of 500,000 men, recruited individually, wearing a UN uniform, and controlling a nuclear force composed of 50-100 mixed land-based mobile and undersea-based missiles, averaging one megaton per weapon; (3) governmental powers distributed among three branches...; (4) compulsory jurisdiction of the International Court."
Does this sound at all American?
