Now look at the plot: after Khan attacks a meeting of Starfleet big shots in a conspicuously Pentagon-like location, he transports to the Klingon home world faster than anyone can say, "Hey, that guy looks way too white to be named Khan." Kirk is ordered by Admiral Guy Who Played RoboCop to pursue Khan with an armament of 72 experimental torpedoes, but Kirk eventually learns the truth: Admiral RoboCop had been forcing Khan to develop weapons to secretly give Starfleet a military overhaul and jumpstart a war with the Klingons, which he considered inevitable. That's basically the Truther narrative: that bin Laden was nothing but a patsy used by American warmongers to justify the Middle East invasion they wanted anyway.
It's not like there were already dozens of previous terrorist attacks that could have been used as a flimsy pretext to invade.
If funding the enemy of an enemy only to later have that first enemy attack sounds familiar, that's because it's basically the gritty origin story of the Taliban, who originally fought the Soviet occupation of Afghanistan with weapons and training from the US. Hey, did we mention that Kahn's origin story is that he was a genetically engineered soldier designed to fight an old war?
The Soviets didn't stand a chance.
Also, 72 torpedoes may seem like a totally random number, but it's different from the totally random number the original Star Trek series came up with. The torpedoes in Into Darkness contain Khan's cryogenically frozen crew, but his crew complement was originally 84. It seems like either an arbitrary change or a fact-checking error, but 72 also happens to be the number of virgins that people who don't understand Islam very well believe are promised to suicide bombers in the afterlife. Coincidence? That's your call.
