Tibet is not (and was not) defended by a nuclear superpower. South Korea and Japan both have United States military bases and troops stationed there.
I am willing to bet all of the money I will ever make in my lifetime that China will not invade either one as long as they remain under the US nuclear umbrella.
If historical claims are valid, then Mongols would be very happy to claim large swaths of land. Or if more recent claims are to be taken, then the Brits have claims over quite a large amount of countries.
Historical claims are meaningless and are just an excuse for expansion.
I 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.
> This does not mean that China is going to go to war over them, certainly it won't go to war with India.
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.
China was happy to invade Tibet and assimilate it's population.
Hard to believe that a government who claims all of South China sea, large parts of India (Arunachal Pradesh) does not want to expand.
Or do you think people of Arunachal Pradesh are also Chinese?
