The objective of the Hindustani peasants is to undermine (with talking points Like 65, 71) the Pakistan-China alliance.
They bring up 1971, in 1971 China was in no position to help Pakistan as it was going through the
Cultural Revolution and suffering from internal instability, that China, is no longer. Today, China is very powerful and stable. Though this fact escapes the Hindustani peasants.
So what they try to do is try to convince Pakistanis that China isn't going to support Pakistan in a conventional war, they try to cast doubt, it's a really simple technique that you have to expect from them as they are trying to cover for their own insecurities.
I think one day we will settle this issue, when both Pakistan and China launch joint military strikes against Hindustan. Both Pakistan and China have territorial disputes which they strongly lay claim to. Not to mention China issuing separate passports for people in IoK, making official statements like "China's border with Kashmir isn't border with India", increasing military infrastructure and troop presence on the China-Indian border along AP region.
Of course, the Hindustani will say China and India have large economic trade and it's not in China's interest to attack India, who are they kidding? As if China needs trade with Hindustan. String of Pearls strategy is in their face and yet they still deeply asleep in their slumber of stupidity or there being dishonest.
It makes perfect sense for both Pakistan and China to launch joint-military strikes against Hindustan, AFAIK in 1962 was China encouraged Pakistan to attack Hindistan, but foolish Pakistani politicians under influence of Western countries and diplomats encouraged Pakistan to remain neutral, a big mistake.
As for now let the Hindustanis play their game of words, in future, and I say this with reason and strategic interests of both China and Pakistan in mind it is likely both countries will wage a joint war against India, it is no wonder Indian General stated his military is prepared for a "two-front war"... Even he by his own admission accepts this possibility as very real and actionable.
