There is no glory in war. War is a tool to establish supremacy built on the human tendency of greed & selfishness. From time immemorial, government across the world spend lots of money and resources in order to propagate patriotism in people and boy it has worked like a charm.
We are so brainwashed in to thinking that a soldier exhibit courage, valor, grit, gumption and what not. We are conditioned into thinking that they are sacrificing our lives for the country. Truth is far from the projection. Nobody wants to lose their lives and live in horrible environment of fear & fight.
