I always thought Wood(or whoever wrote this) got the idea for Total War from a thirteen issue epic that ran in the Operator 5 pulp in the 30's called "The Purple Invasion". It's pretty much the same idea, except that the destruction and anarchy are much more excessive. I wasn't around to read these when they came out, but Steranko gave it a huge write-up in his chapter on the pulps in the History of Comics. I've since read it in reprint and it's pretty mind-boggling; would make an amazing series on TV or in comics, assuming we don't just accomplish all the destruction by ourselves.
Yeah baby! These are part of the few comics I saved from the 60's. I agree, what a great TV series it could be.
