In full context of the interview, he’s just jumping off of a point Cameron makes first actually. It really is more about patterns than him citing specific source. Like, “today’s [insert insurgency here] are yesterday’s Viet Cong”, etc, etc.

Tangential but I somewhat recently read a book of interviews with John Milius, where he talks about Lucas’ unmade Apocalypse Now, describing him and their company as extreme hippie radicals - maybe Lucas is being honest about the original intent in SW; however overt it would’ve been just didn’t make it through the notorious editing process 🤷

also just kind of an insane story, they were gonna do that shit in the actual war
