>I'm pretty sure Google can't wage war
No, but such a service can be just be used to help win wars, blackmail politicians in other countries, spy on foreign businessmen and policy influencers, and those sorts of things...
Besides corporations have a long history of meddling with local politics, hiring thugs to kill people (e.g. strikers or union leaders), even helping install dictatorships.
Of course such things happen in such ways as to provide all ways of "plausible deniability" to company executives. It's not like they'll send a fax asking for such things -- "just deal with it" communicated to some local managers implies more than enough.
