The most important contradiction of this epoch is between the existence of the nation state and so called globalisation. But globalisation under a crisis ridden capitalism is too weak to abolish the nation state. On the other hand the nation state in reality becomes so obsolete that it cannot fight back against the onslaught of world imperialism. Hence the aggravation of the economic crisis will give rise to greater turmoil and social explosions. The rulers of the Indian sub continent can't afford a war.
History is witness to the fact that every war ended up in revolution.
After the 1965 war there was the glorious 1968-69 Revolution in Pakistan. After the victory of India in the 1971 war in Bengal, there was a mass workers' movement and general strikes of the Indian proletariat. This led to the overthrow and subsequent demise of the victor of that war, Indira Gandhi. If there is a war this time round it will result in total subjugation of the nation state to imperialism, if not its annihilation. But in the aftermath of a war a revolutionary upsurge of unprecedented proportions is inevitable.
