The Chinese fought well in the korean war.. Bad to stereotype people as war like or non warlike. We can say that the Chinese of 1950s were pretty comfortable with war, since they were subject to repeated japanese invasions, and then civil war. But, the chinese of today have not fought for 4 decades. So, this will work in India's favour initially if there is a war..
Even the fresh american troops first sent to africa during WWII were left shell shocked when they first faced General Rommel in battle.. But, they quickly got used to war and slaughter. Once, the shooting starts, this advantage that India has will diminish with time..
It's not about soldiers getting used to the war & slaughter.
It's about the people of the country, the father, mother, wife and Children getting used to hundreds/thousands bodies coming back.
India is used to soldiers dying,
we have been losing soldiers, even officers quiet frequently & the people as a whole see the martyrdom as an honor. GOI irrespective of which party is in power, has been fairly consistent in honoring the braves lost in battles.
India as a civilization responds to martyrdom with pride and anger.
China & Chinese people on the other hand have been living in relative peace, lot of them leading very comfortable life with rising income & opportunity. They have not lost soldiers in a long while, until a month back. And more importantly, these soldiers were not lost defending their land.
How the Chinese people & relatives of the fallen respond is a mystery. A hundred you can probably. Thousands of dead, it's game changer.
It's not like some one invaded CHina and are killing these people. It's the PLA which invaded another country and getting killed.
US did not lose Vietnam war in Vietnam.
They lost it in USA.
As aggressor, CCP would have it pretty hard to sell the dead bodies to Chinese people.
