alt Hacker NewsI did not comment on the "validity" of the claim, just explained its rationale and history.
Chinese territorial claims in general are not "an excuse for expansion", they are rooted in territorial losses at the end of the 19th century and during the revolution of 1912 with the formal aim of recovering them. They also predate the PRC as you'll find that the ROC/Taiwan has the same claims for the same reason. This does not mean that China is going to go to war over them, certainly it won't go to war with India.
No need for drama or hysteria over those claims.

Then why make a claim? Claims are made to prepare the domestic audience so that when war comes there is home support for the action. It is not made lightly.
The Chinese are definitely taking action in the South China Sea. It is not just words.
