WAR & PEACE! Are they the same thing?

Peace is a ideal and a concept that I don't believe has ever existed or can exist in this realm of reality.

Survival is a war, so as long as you live you are at war with your survival.

The term "Peace time" only means 'not war time'

Death is the only possibility of Peace.
And even death may not exist.

Yes. Much of the confusion is caused by definitions that are either too general or too specific, or are dependent upon the definition of the OTHER term in the pair (Peace is the absence of war, for example; then the problem becomes one of the precise definition of war).
This is especially true when discussing modern warfare, where there are no formal declarations of war, no traditional and uniformed armies, and no clear chain of command.

I think Kierkegaard wrote a little book about that: either or

But yea, they're interdependent ideas. That gives you the intuition that they're two sides of the same coin. Kierkegaard was both right and wrong.... which are interdependent ideas.
