Anyway....
Peace is largely a subjective concept... and something of a continuum, usually.
Most people walk around, delusional. They can't conceive that anyone out there would try to harm them or that anything bad can happen. They are "at peace" and "going about their daily routine" unaware and unprepared. For this to happen, there must be relative social, economic, and military security to allow for reduced conflict over basic needs and paranoid maneuvering.
Then you have other people (like me) who like to give themselves distance, prepare for conflict, and make the effort to be alert... in the end - you can't be watching for every single thing that might happen at any given time (unless you fancy having mental breakdowns and panic attacks) - but you can do a pretty good job of catching on when you need to ramp up your alert. ... But are you 'at peace?' ... You're not fighting - but you're always making efforts to remain secure and to not be victimized or forced into a confrontation... It's a stance that requires strain on your limited resources to maintain and can, at times, leave you restless.
Is that really peace?
Then you go to the people who are always combative and aggressive. They tend to throw their weight around and to simply clobber obstacles (at various scales and in various ways within the appropriate context). They tend to be the aggressor and often intimidate more wary parties into compliance.
Is that peace?
Then you have people who don't care and who will simply kill problems without fuss. They accept life and death within the various power struggles and don't seem to take issue with the idea that they could die or that they may have to kill.
Is that peace?
In the end - different people find it comfortable to deal with conflict in different ways. Some ignore it, some prepare for it, others create it in an attempt to control it, and still others choose to lance it as it arises. I dont think a -lack- of conflict is really possible, only changing the forms it takes to be more comfortable and its consequences more acceptable to the parties involved.
Conflict, itself, is a natural part of the universe. It is ingrained into physics, itself. As a system becomes more energetic, the independent properties begin to assume more degrees of motion that can interact constructively and destructively. To make a system behave uniformly with no internal variation to conflict is to, basically, remove all useful energy from it.
I'd rather have an energetic world. Even if it means I may have to rip open a man's chest and eat his heart to gain his power.
... Wait... wrong universe...
