When Godzilla came on land in Tokyo, we learned he was extremely
sensitive to light. In fact, if anything, bright lights make him burn with
intense rage . . . I imagine that’s the result of having been burned by
hydrogen bomb tests in the past. No doubt he remembers. I imagine he’s
learned to react to lights in strange ways, so perhaps we can use his
reactions to our advantage. We could drop flares to lure him farther out to
sea . . . This is a rather passive way to deal with the situation, but it’s all I
can come up with for the moment . . . The most important thing, in my
opinion, is to implement a strict blackout policy . . . I hope you in the police
and Self-Defense Forces can do that for us.”
