The world has seen two wars with each being called a war to end all wars during its bloody days. On close examination one can observe that without the stockpiling of weapons by the belligerents these wars would never have happened though they were carried out with peaceful intentions which we all know how that turned out. Are we not facing the same problem again? We sit back and watch our countries have bunkers filled with nukes all in a bid to protect our peace. Is this pretence not a preparation for a third war to end all wars?
The world has seen many, to many wars in the human history.
We can freely say that numerous wars and conflicts slowed down the development of the human race.
Everyone starts the war to win and destroy the opponent so there is no peaceful intentions here (unless we believe in statements by politicians lol).
We don't know if and when third world war my happen but such war would completely destroy our civilization and would not be a winner.
So, better avoid any such global conflict in the future or we will see the end of our world.
