Kashmir-Himaliyan Blunders Continued

The biggest mistake India committed on the Kashmir front is not to refer the issue to UN and declare ceasefire or accepting the demand for plebiscite. However the biggest blunder was to accept the invitation of Maharaja Hari Singh and send the troops to Kashmir valley.
Although reluctantly our leaders accepted Jinha's theory of two nations and given consent to partition of India and the principal on which India was partitioned between India and Pakistan was religious majority. That's how Punjab and Bengal were divided.
Sighting the same principal, we did not allowed Nizam of Hydrabad and Nawab of Junhagarh were not allowed to join the Pakistan. So India had no legitimate claim whatsoever on Kashmir Valley. At the most it could have staked the claim on Jammu and Laddakh.
But once we accepted the invitation to send the troops to Kashmir, we left the business of occupying the Kashmir unfinished and created the trouble for ourselves, which we don't know, how to tackle, even after 63 years of Independence.
This also clearly shows, there was no well thought out strategy behind sending troops to Kashmir. There were no clear political objectives set by India's then rulers when they sent the troops to take on so called tribal militia. After all war is a diplomacy by other means.
When China decided to occupy Tibet, political objective was clear, it wanted to create buffer between itself and its mighty Western neighbour India (This may sound ridiculous in today's circumstances, but back then we were on the same page with China both in terms of economic and military might. In fact India's army was better trained and armed thanks to British rule).
Then another mistake we made was, we made no attempts to change the demography of Kashmir as China did with Tibet. In fact we went on to add Article 370 in the constitution and ensured weed of separatism never dies down in the valley.
Having said this, now only practical and honourable solution to both India and Pakistan to solve the problem is to accept the LOC as the international border and settle the issue for once. We were close to achieve this goal during Indira-Bhutto talks after the Bangladesh war but wasted the opportunity and allowed the enemy to go lightly like good Hindus.
But now, we must not waste any time and arrive at settlement on Kashmir issue at earliest and move on. We can't allow our nation to bleed and hamper our economic progress and more importantly, if we remain too preoccupied with Kashmir and Pakistan, we may never able to prepare ourselves to take on the next big challenge before us i.e. China.
