Unfortunately this is not wholesome at all; those Indian soldiers are getting the Chinese soldiers to say "Jai Shri Ram," which is effectively a Hindu nationalist slogan. It's the kind of slogan that Hindu nationalists chant directly before engaging in pogroms against Muslims and Christians. They're doing this today of all days because this week Hindu nationalists are celebrating the opening of a temple to Rama at his supposed birthplace that was a sacred mosque (the Babri Masjid) burned down during the 1992 Hindu nationalists riots that killed hundreds of Muslims.
EDIT: In fact it was exactly this slogan that the Hindu mob shouted right before burning down the mosque, so a very obvious fascist dogwhistle here.
Fair enough, I'll definitely agree that it's better than open warfare between India and China. Thankfully feels like we're lightyears away from that outcome, especially given BRICS.
