Ok, let’s get one thing straight. 9/11 is not a justification for secret government operations. 9/11 was a retaliation for decades of secret (and not so secret) government operations. The U.S. initiated 29 regime change actions since the end of WWII, with many middle eastern and Muslim countries (Iraq, Syria, Iran, etc) being targeted multiple times. To think that the events of 9/11 were not a response to U.S. military and CIA operations in the middle east isn’t evidence of ignorance. It’s evidence of utter delusion.
That they finally retaliated should be no surprise. The surprise is that it took them so long.
U.S. government secrecy is not the answer to terrorism. It’s the cause of terrorism.
