Why can't India afford a war?

Most of us want our country to give Pakistan a clear answer. We don't want proxy wars, we want them to know our power. And how is that possible — a war.
    Or maybe not. Because wars are not so good.

These are the main things we might face due to a war—

Economic crisis- We are the world's fastest growing economy. The fast growing GDP had a minor halt due to the recent demonetization and we do not want our country's economic progress to stop completely, right? 

A war will cause great loss to infrastructure and lives. We will be spending large amounts on defense equipments and on rebuilding the infrastructure that was devastated due to war. This might cause a big standstill on our country's economic growth.

Danger of losing something else, or a world war- A war never goes unnoticed. If the war continues for a long time, we risk a world war.

China might not help Pakistan directly but seeing India on a warfront, China might attack Arunanchal Pradesh, to get the territory they call 'Aksai Chin'. With warfronts on two sides, India might find it difficult to cope up with this.

Life of countrymen- Who wants our countrymen, specially our soldiers to die? We do not want a huge loss of life, of both civilians and army men. With a war going on it is inevitable losing lives. Nobody in this country, except those who live for Pakistan, would want our brave soldiers to die in large numbers.

A war is never good. It always loss- of lives, of culture, of relations, of biodiversity and of economy. Every country on this planet would try to avoid a war and tries to resolve any conflict by negotiations. Even we did not get our independence by fighting.
