Why is Wonder Woman in handcuffs on the cover of one of her forthcoming issues? Perhaps for no other reason that it would please Moulton and anger Wertham. But I suspect it has something to do with the fifth summer miniseries, "Amazons Attack".
What's that? There is no such miniseries, you say? True enough. But, according to Devon (who erreth not) at Seven Hells, there was supposed to be. But the whole thing got too bogged down and the project was abadoned so as not to hold back the other four, "The Spectre's Hissy-Fit", "Batman Enables the Enslavement of the World", " The Secret Society of Unpleasant People", and "Putting Rann Out of Our Misery".
The set up was there: Themiscyra rudely plopped by Hera off the coast of the U.S., where it was suddenly cordoned off by warships. The Amazons were about to go to war with the Americans, I tell ya. DC's not going to let the ideas go to waste; without "Amazons Attack" the ideas will find there way into Wonder Woman, probably right after Donna is brought back.
The handcuff cover lends credence to this theory. With diplomatic immunity, Diana wouldn't really be susceptible that kind of arrest ... unless, say, her country was at war with ours?
