There is something called multitasking. You don't sleep on security while developing the country.
Then you are the first one who should realise that this is not some Qing, Shang or Manchu era and retreat back to your actual territory.
Please. The vast majority of Tibetans resorted to China only when the British with their Indian slaves came barging in. It was China who defended Ladakh and Tibet for centuries, asking for nothing in return. China has been a tolerant, pluralistic multiracial society for hundreds of years.
India is a hellhole full of hate and race murders. You can choose to be someone's dog in Delhi, before you get beaten to death in the street, but don't speak for your people. It's clear on these forums that you don't speak for everyone.
If anything South Tibet can always join the Republic of China, where you will get better rights than you can ever imagine, and all the worthless crap like democracy you like so much - without the racial rapes and murder. Taiwan is even wealthier than India, which shows just how sad India is as a nation.
