This week, host Dev Goswami and defence expert Shiv Aroor talk about India's nuclear setup. They dive into why India decided to go nuclear back in the 1980s and 1990s, explaining the concept of the nuclear triad. What does it mean, and why has it been so challenging to complete the submarine part of this triad? And why do we need submarines like the INS Arihant or INS Arighat to finish the triad?

What exactly can India do with its nuclear weapons? And why is there so much secrecy surrounding these operations?

Let's imagine for a moment: if a nuclear attack were to happen, what would it look like?

And they ponder the paradoxical nature of the nuclear world. What is it? Tune in to find out more!
