India deploys 12 nuclear warheads for first time; where do China and Russia stand?

India has deployed 12 nuclear warheads for the first time, a significant shift in its nuclear posture, according to SIPRI. With a total of 190 warheads, this move signals a move towards a more operationally ready sea-based deterrent. This development occurs as global nuclear arsenals expand, with China rapidly increasing its stockpile.
