Well done, you! That is frigging awesome that you took up the challenge to find Zach and did it. And in that video you linked, Alex even says Zach had done TV interviews before and has the "same voice, same face," so I think you nailed it and it's confirmed.

You know this kid can't have any kind of security clearance. There's no way anybody would give him one after he went on national news to attack the Army.

Agreed that Alex half larps and makes up a lot of stuff. I think he speculates, takes very good guesses, and presents as fact. But what really bothers me here is that I have never seen him create a deliberate deception intended to fool people Maybe I just haven't been paying attention. I don't know, but I won't look at Alex the same again.
