Any time Uncle Sam sees an opportunity to get his greedy little fingers into another cookie jar he'll take it. Wealth and the lust for power are more addictive than the hardest drugs. Once you got it you want to keep it and to hell with who don't like it. Been that way from day one. BTW...this is 2013...the CIA finally admitted that it was behind the coup that toppled the Iranian government back in the fifties and installed the Shah of Iran, a dictator, who himself was toppled in the seventies. And you wonder why the Middle Eastern countries hate the US.
Sixty years it took them to admit the truth. In the early sixties it was Viet Nam, a CIA controlled 'war', one which could have been ended within six months according to a high ranking North Vietnamese official who publicly stated that the US military was far more powerful than previously thought but because the 'war' was controlled by pin-striped pencil pushers in Washington aka politicos, the soldiers hands were tied and they were forbidden to take certain actions which would have ended the 'war' much much sooner. The CIA's role, remember Air America, was handling the distribution of drugs throughout the region. Tons of bucks to be made at the citizens expense. The 'war' ended, for the US not the people who lived there, in 1975. In 1995, twenty years later, Uncle Sam finally admitted it was a mistake going into Viet Nam. This government supported a brutal dictator in President Diem who was opposed, naturally, by Hanoi.
Manuel Noriega was another puppet of the US corporate establishment and was only deposed by the same because his dealings with the drug runners was exposed. He took the fall and Uncle Sam got away scott free as usual. Saddam Hussein was another, installed by the US in Iraq in order for the corporate entity to control the vast oil reserves discovered there in the fifties. Note that since then, some sixty years and counting, that entire region is still unstable and peace is a concept not welcome in Washington. In peacetime you can't make money. Keep the region destabilized and the money flows unabated. Drugs, oil and weapons all controlled by the US corporate entity. The oil will be gone in less than a century but not the drugs and certainly not the weapons and the people who desire them for whatever reason. It is what it is folks so none of this bullshit should surprise anyone.
My two cents.
