That is very relevant owing to the cause and effect of the IA training civilians and later on officers of the East Bengal regiment. Pakistanis always harp on the fact that IA trained these Freedom Fighters ; But why were they trained ? The principle reasons :
1. A Massive Refugee Influx from East Pakistan to WB when the PA merrily went about their Genocide duty in East Pakistan.
2. The oppression and rage rising in the amongst the officers of the Regime about the barbaric nature of the killings and the utter helplessness with which the PA also suppressed the Bengal Regiment, due to which they had to resort to guerilla warfare and for this they required weaponry from India, which India gladly gave. Why did India do this ? One factual assessment was the oppression seen of their fellow Bengalis not by the Razakars and the Jamaat-e-Islamis, but by the Pakistani state itself.
So, what IA did do is provide a covert but unequal support in response to the state-sponsored Genocide of the PA. And hence, the Newtonian doctrine of covert physics.
