Stupid title is stupid. :p
I mean seriously, what kind of title is peace walker?
u r so dumb
It's a fantastic title. It has multiple meanings: one who walks for peace (Gandhi-esque), or a 'walker' (i.e. METAL GEAR!?) that's more pacifistic than the usual brand, with connotations of Cold War-era deterrence - which fits the setting perfectly.

However:
Peace Walker is a nuclear deterrent, a fully automatic one controlled by an AI developed to perfectly mimic The Boss. The AI dev knowing that she would be the only one who could live with causing genocide in order to protect her country, something a normal person could not do.
so yeah... Nuclear deterrence strikes again.
