The Lac has not shifted west since 1962. The proof is right here.
Since no clear, UNBIASED, NEAUTRAL evidence has effectively countered the line google has used for decades, that is the lac that stands, I posted it above for those interested in facts, not preconceived notions. That map is corroborated by historic Inidan documents and even declassifed CIA Maps, including one of the first documents to map the LAC. If anything, the LAC has shifted East, meaning India has gained territory since 1962.
