"But the attainment of peace is not as easy as the desire for it. Not for nothing is history associated with the figure of nemesis, which defeats man by fulfilling his wishes in a different form or by answering his prayers too completely. Those ages which in retrospect seem most peaceful were least in search of peace. Those whose quest for it seems unending appear least able to achieve tranquility. Whenever ever peace — conceived as the avoidance of war— has been the primary objective of a power or a group of powers, the international system has been at the mercy of the most ruthless member of the international community. Whenever the international order has acknowledged that certain principles could not be compromised even for the sake of peace, stability based on an equilibrium of forces was at least conceivable."
-Henry Kissinger 
This is what I am expressing in this piece. Sometimes conflict is necessary for peace. Not revenge but defense and prevention.
