[...] If Militech was behind the assault on Arasaka Tower in 2023, and if there's actual EVIDENCE to support that, then why didn't Arasaka return the favor and nuke Militech? By now there's no doubt the bomb was manufactured by Militech, but that doesn't mean they detonated it. I confess, I'm not a huge fan of the popular theory that Johnny Silverhand, the controversial rockerboy, was behind the whole thing. In fact, I'm not really a Silverhand fan, period. Silverhand was a poser and a blowhard - not someone who would actually follow through on his grandiose bluffs (full disclosure, I just don't think Silverhand would have the balls to pull off something like that). Let's think this through - who hates corporations the most? Nomads, obviously. Remember that mass-market BD called "Badlands Raid" from the 20s about a band of nomads who attack a Militech convoy? Well, guess when it premiered? That's right - on the night of the attack. Coincidence? I think not. Yes, yes, there's a Silverhand cameo in there somewhere, but that's just a marketing ploy - a BD scrolled by a bunch of cactus-huggers wouldn't sell for an enny without a recognizable face. But I'm more intrigued by the main actress - how is it she didn't star in any other production despite "Badlands Raid's" huge sales? Where was she during the attack?
