Neither side have centralized command and control, no centralized launch control, both Indian and Pakistani nukes are practically unsafe and neither country has a nuclear triad nor hardened launch capabilities that can survive a first strike, the only 2nd strike any of these countries would get is due to the sheer incompetence of their opponent.
What’s worse is that both sides also lack proper early warning systems, reliable IFF, centralized communications, and essentially everything needs to ensure that no one is going to make a huge mistake.
India and Pakistan are both a joke sadly for the rest of the world not a particularly funny one, and what will start with them won’t end with them since Russia, China and the US would get dragged into the situation.
One of the biggest criticism of the nuclear non proliferation treaty is that it lacks the provision to deal with nations that achieve break out of full nuclear capabilities and allow the nuclear power to provide them with guidance and the tools to actually secure their nuclear arsenal.
To put things into perspective China only now is establishing a centralized and fault tolerant command and control infrastructure with continuity of government and military command, both the US and Russia have been constantly miss identifying anything form wild geese to sounding rockets as possible first strike candidates and you if expect India and Pakistan to handle these issues with competency then you might need to reconsider what you define as such.
