This article gives an idea how the votebank and the geopolitics works in the subcontinent.

No it doesn't, it assumes the reader already knows this. As someone not familiar with Indian politics it was very unclear that 'The Congress' refers to a political party instead of an institution.

BJP (the potential) is the reason the original Muslim League wanted a separate Pakistan.

RSS didn't even spare Gandhi. Jinnah's assessment of the extremist group eventually becoming the majority turned out to be true.

Modi basically spent his first two terms throwing away the leverage of the nation's massive IT industry and solid relations with Russia for getting dumped by Trump via tariffs and visa bans.

Not to mention his double air force fiasco with Pakistan.
