Nehru did not give away third of kashmir, its because Indian forces could not proceed further, after nearly 1 year 2 months of hostility.
Aksai Chin was not ceded by nehru, it was done by pakistanis who had captured it.
I am not sure India could capture tibet that time, when she was too busy solidifying its hold on Indian mainland. 62 was a disaster because of difference between perception of such capability and reality.
Ontopic: Border killing is not same as capturing your land. And most of the time IA will do something similar / has done something similar.
Regrettably, your knowledge of history appears to be scant.
Let me indicate how.
1. If you read military history books you will realise that when the 161 Brigade was about to link Uri with Punch, they were halted and brought back to the line we now occupy in Uri.
2. The Army was pressing on, but Nehru, the Great Statesman, played into the hands of the West sponsored UN and agreed to the ceasefire. The result - one third of Kashmir remained with the Raiders (Pakistan).
3. Nehru did not cede Aksai Chin. He sat impotent and twiddled his thumbs when he was being told that the Chinese had occupied it and had built a road. Thus, he GAVE AWAY Aksai Chin!
4. I am afraid you are clearly short in your knowledge of history, seized with a deficit in facts on all issues that you have postulated on. Pakistan did not cede Aksai Chin. It appears you have never seen a map either. Let me educate you:
They ceded Shaksgam Valley to China.
5. In the 50s, China was assisting North Korea to fight the American Forces and at the same time were occupying Tibet against Tibetan resistance, especially from the Khampas.. Therefore, it was fighting two wars. And the PLA at that time was not the PLA of today. Tibet asked for assistance and Nehru was more keen to appease the Chinese!
6.A most ridiculous statement that 'border killing' is not the same as 'capturing your land'. In other words, you say cross border killings are par for the course. Wunderbar! You feel India is doing the same? How come the Pakistani politicians and the Pakistani media that is so shrill to condemn India has never displayed this shrillness when India does trans border killings? The reason is simple - India has not done it!
I would recommend you first hone up on history and events before trotting out bunkum that is a total waste of time and bandwidth.
