暇つぶしにみた映画Snowdenに日本に関してこんなセリフがあった。

Course we tapped the entire country anyway.
And we didn't stop there, 'cause once we owned their communications systems,
we started going after their physical infrastructure.
We'd slip these little sleeper programs into power grids,dams, hospitals,
and the idea was if the day came when Japan was no longer an ally ,it'd be lights out.
