nah. it's because when you want a hierarchy, you need thugs to maintain that hierarchy, and without war, allyour thugs are evergreen noobs. without war, there's no 'them' to pit your populace against so they identify with their oppressors. without war, it takes skill and finesse to exploit foreign peoples for resources (as china has shown, with great aptitude, because they're what the competent people in the US government wish they were).

so you need war. it also helps make people stupid and obedient and justifies shit like the NSA. which is nice.
