I personally feel that Saudi Arabia should have gotten a boot up their ass too. They were never shy about supporting AQ. Sadly, there were other interests at work other than actually dealing with our attackers and their supporters. Pakistan also likely should have gotten a few surgical strikes, aside from. However, invasion of those countries would have likely sparked WW3; so I'm guessing we took what we could get in an attempt to send a message. The least we could do at this point is cut off aid money to all these damn countries that have a history of trying to kill us.
I'm well aware the US supported the Taliban during their fight against the Soviets. If nothing else, I'm fairly sure we were providing foreign aid to their country. I'm sure not all of that actually went to "aid". I still maintain that the invasion of Afghanistan was entirely justifiable. You didn't really state a point to your statement; was there one?
Blowback.... In this case Foreign aid is the catch all term to cover Arms, COIN, FID and paramilitary action. Obamas admin. is supporting these guys in syria and libya, what happens when that gets boring and we're out of afghanistan? at least all conventional forces anyway...
The device used in the boston attacks was the exact same spec IED the CIA taught the muj to make back in the '80's this also extended to supporting jihadists in bosnia, they learned the same things too. Benghazi is another example and obviously 9/11 the big wedding was the most public.
Apart from arms & explosives training, some of these jihadists were given extensive training in intelligence tradecraft - add this to any paramilitary training and it makes for a formidable opponent that has received, to a degree, the same training operations folk in the clandestine services would receive.
I'm all for cutting off aid to countries that have said history but at the same time the US cannot in a covert or clandestine capacity support, in anyway, shape, form the very people we've been fighting and the organistations and ideology we're are trying to put down. I hope this is something that will be addressed because i cannot stress enough the severity of consequences resulting from lack of foresight and disregard for history... that old insanity addage comes to mind...
