Yes with a coward as Nehru, we have had millions of problems, to name a few.... linguistic states, bleeding public sector units, a sycophant congress party, a legacy & dynasty of his own, etc etc.
A week Nehru is the cause of the POK (Pak occupied Kashmir), when the Muslim invaders were being hammered & killed by the Indian army, Nehru personally pleaded with General Kariappa & Thimaya to halt the assault as Muslims were being killed in large numbers(in an invasion by Muslim terrorists who else could have been killed except the Muslims).
Such was a coward Nehru & the result is what we all know today. Just forget Tibet, our own Kashmir, a huge part of it called POK is lost for ever, although we all have been taught in our schools that the entire Kashmir is Indian Territory.
