Dear Brother Jamal,
I wrote; " Now China, since they have damaged the world, must be accountable and must pay back in international courts. "
I meant " Answerable, accountable, trialed" , Monetary compensation is secondary.
All international crimes are suppose to be settled same as
The Nuremberg trial.
Libya's Panam plane downing on Qaddafi's orders. After 50 years Libya had to pay to all dead passengers.
US had to payback Iran 40B dollars during President Obama in 2016.
Russia still have to pay similarly for downing Malaysian flt over Ukraine few years back. ( That may not happen due Russia's power)..
Of course there are crimes which went unpunished. Reason are various political and international possibilities.
We hope one day India will be tried for its mass killings in Kashmir.
