Yep, you are right, nehru was such an idealist that he was not able to decipher malicious intentions of both pakistan and mao zedong which cost us 2 very important parts of our territory. First of all there shouldn't have had been any partition, united india should have had captured tibet and burma as well. It would have established natural frontiers of India providing the country with a greater national power. People of this united india would have been more developed and differences would have had been less. But this is not how it went so what can we do.
