Aray Pappu G, you got it all wrong... this Bengali Spring was supported by the USA against the Indian puppet Hasina Regime...
It all started when India wanted to show the world (and more importantly its insecure Hindu nationalist voter base) that it is now an independent supa powa who doesn't have to side with China or the US, and that Hindus are no longer slaves of Muslim invaders. You know, the usual bhakt BS.
The first example of this was the Balakot strike. This backfired as it set a precedent for Pakistan using its conventional power to punish India for its transgressions.
The second example was picking fights with China. This backfired as India lost 1,500km of territory to China. Even in the Indo-Pak war of 1971 when Pakistan was engulfed in civil war, Pakistan had a net loss of about half as much territory to India in the same Ladakh sector.
The third example which sealed India's fate was a spree of murders of minority activists on Western and Pakistani soil. First we saw Pakistan's retaliation, which was predictably to turn up the heat in Kashmir, burn INS Brahmaputra to a crisp in Mumbai (per Indian media), etc.
The more interesting thing is the USA's retaliation against India. The US said, "India, you think you're an independent super power? Fine. We will no longer consider you an ally in our fight against China. We will take necessary steps to re establish our influence in the region."
It's started with a newfound indifference to Pakistan's support for Kashmiri fighters. Then, the Americans declared they would out-do Chinese investment in Pakistan.
Now, the US supported the "Bengali Spring." The Indian puppet regime was brought down in a bloody revolution, and replaced with a widely popular anti-India, pro-Pakistan/US govt. A Govt Led by the same man who told India he would not spare the Seven Sisters if India disrespected Bangladesh's sovereignty.
If anything, the US will probably give Pakistan some AIM-120Ds and F-16Vs to "fight the Taliban" again
