Previously it was PLA going against India.
Then it went to govt level.
India started trade war
Now it went to national level. Where civilians started to hate India.
Thats how it gets escalated to war.
I recon this piece of PLA's media work, ie. choosing the best moment to make public announcement of the casualties, reflects a fact that the Chinese Government has opened a door for firearm use in next clash.
Remember the communities in China, as of its cultural tradition, do give the government and PLA flexibility to maneuver in difficult situations, such as choosing best time to publish the casualty data. So if the government publishes the data, that means the government has put the pressure on themselves and will be committed to future counterattacks in a more effective and efficient way to minimise the casualties. That can only mean firearm use.
Some sources indicated that firearm use did happen after the Galwan clash, in which PLA encircled and shot dead a squad of Indo Tibetan Border Police who fired some bullets first in a confrontation.
