It was a False-Flag operation setup by the Globalists that control the central and world banks (war profiteers) that control the American military and corporations that control the American government (among many other EU governments etc.), mass media and educational institutions (even major world religions) to get the programmed complacent American sheeple to support the troops going to the Middle-East to wreak havoc by death, destruction and drug (opium) smuggling.
Furthermore, to advance the Globalist agenda by increasing the wealth of corporate interests abroad (e.g. Haliburton etc.) and to control the proverbial center of the 'crude' chessboard for leverage over rising economies (i.e. India & China) need for oil and to impose New World Imperialism on non-conforming dictatorial governments with a regime change, beit direct or indirect with secret "black ops" posing as national rebels.
All the while deminishing and destroying America's middle-class via sending manufacturing and production jobs to countries where labor is "dirt cheap." Moreover, passing laws which give government entities like TSA, Homeland Security and local police more powers with legal immunity to harrass and rob American citizens or thier rights, freedom and savings as well as their property.
[ For America's wealth, it's kind of like that movie "Oceans 13" where they rob the casino owner blind of all his wealth in one night. ]
Ultimately, to bring all of America to its knees; gladly submitting to the government for thier needs, such as healthcare, housing and sustanance. Of course this doesn't happen so easily... not until the vast majority of Americans are rounded up like cattle and sent to "Re-education Centers" (i.e. Fema Camps) where, as a result, the population is greatly reduced; leaving only two classes of people: the wealthy elite and the poor pawn peasants.
To assist in maintaining this order, since the might of America's military is turned over to the whims of the U.N., America will be in for another unexpected surprise as it becomes occupied by several foriegn armies, possibly entering the country by the way of the many underground tunnels virtually stretching across the continent. These tunnels are massive; big enough for heavy machinery and personnel carriers. So they might seem like locusts as they appear suddenly in the Midwest and spread out in all directions.
And there you have it. History repeating itself once again. Another empire has fallen.
