The Indian state of Arunachal Pradesh (which China claims as "South Tibet") is not shown as a part of India in the Indian map, as a hat tip to their political masters the PRC. And the Indian state of Jammu and Kashmir is also shown as, I imagine, "disputed" with a dotted line.

Would you say India are their political masters if it was shown as being Indian? Even Google Maps in the US has dotted borders alongside both sides to show its disputed.

Historically, geographically, culturally, the area was always part of Tibet. It was the British that drew the McMahon Line and claimed it was part of India. China never once recognized the line. When Mao won the civil war in China they went on to conquer Tibet and again considered the whole of Tibet theirs.

India's claims to the area rest solely on the british-drawn lines. In reality, the whole of Tibet should be Tibet and allowed to either self-govern or choose which nation they should be a part of

Correct me if I'm wrong, but isn't it disputed, with heavy border tensions and all? I'm not claiming India doesn't control it, and as a Swede I don't know much. But that's about the one thing I thought I knew about Kashmir.
