A reader explicates one of the many ways DC Comics stinks:

Jonah:
A recent episode of the “Justice League Unlimited”
show on Cartoon Network dealt with this
superheroes-interfering-in-the-affairs-of-sovereign-states
theme, too: in it, the North Koreans (or perhaps the
Chinese; I don’t think it was exactly clear) build a
ridiculously huge, nuclear-powered, radiation-leaking
robot and accidentally lose control of it, causing it
to stomp around the countryside irradiating everything
in sight. Green Lantern, Captain Atom, Supergirl, and
Green Arrow fly off to investigate, but the North
Korean authorities, keen to cover the matter up, turn
down their offer to help, insisting that they have
everything under control. Green Lantern asks Martian
Manhunter for advice, and wonders if the Justice
League shouldn’t simply destroy the robot over the
protests of the North Korean government (it is, after
all, probably killing thousands upon thousands of
people with its deadly radiation even as they speak).
Unbelievably, MM throws a fit, testily explaining that
the Justice League can’t go around helping people who
don’t want their help: that that would be akin to
“imposing their will” over mankind.
I think if I were Green Lantern, I probably would have
used my ring to generate an oversized hand with a
middle finger extended at MM before flying off and
saving countless innocent lives. Cartoons these days!
PS. The magic spear used by Hitler to keep Supes and
the others at bay during WWII wasn’t just ANY magic
spear: it was the Spear of Destiny, the one used to
pierce the side of Christ during the crucifixion. Not
sure how DC came up with THAT one…
