While some fall into the folly of assuming that every conspiracy-theory is meritorious simply because it is possible, even though it has no concrete support -- others run blindly to the other end of the spectrum and flippantly dismiss anything that even sounds conspiratorial, regardless of the amount of support it has. A good middle ground would seem to be to maintain a healthy suspicion toward any power-structure whose ability to operate clandestinely makes it largely unaccountable in the public sphere, while reserving final judgment until all of the facts of the matter have come to light (or as many as can be discerned given the nature of the case). And if one should question whether the USA has the ability to operate in such a clandestine manner in the global sphere, making bed-fellows out of our enemies only to use that alliance to a strategic advantage (while the public remains largly ignorant until after the fact), I might remind you of the Dixie Mission's approval of the Maoists, followed shortly by the US backing the KMT in the Chinese civil war; and Eisenhower's formal recognition of Castro, followed shortly by the Bay of Pigs invasion and Operation Mongoose. Money is a powerful motivator, and history shows time and again that it is often-times a more valued commodity than human life or civil rights.
