Introduction
India did not test in 1998 because it suddenly faced annihilation. It tested because the legal and technological window for keeping a nuclear option open was closing, and because status and domestic politics had made ambiguity unsustainable.

Body
1. The old default was principled and cheap: Nehru sought a standstill agreement on testing in 1954, Rajiv Gandhi's Action Plan of 1988 proposed time-bound global disarmament, and India rejected the NPT of 1968 as nuclear apartheid while keeping the option open.
2. Recessed deterrence was the doctrine: the 1974 test produced capability without weaponisation, what K. Subrahmanyam defended as an option rather than an arsenal.
3. The multilateral path closed first: the indefinite and unconditional extension of the NPT in 1995 made the P5's privilege permanent and voided the bargain of Article VI.
4. The CTBT made the closure coercive: its entry-into-force clause named India, and Arundhati Ghose's refusal — not now, not later — signalled that signing would freeze India as a threshold state forever.
5. China was named as the reason: Vajpayee's May 1998 letter to President Clinton cited the 1964 Chinese test, the unresolved boundary and Chinese missile and design assistance to Pakistan.
6. Pakistan supplied the proximate trigger: the Ghauri test of April 1998 showed a deliverable capability that ambiguity could no longer deter.
7. Technical necessity mattered: boosted-fission and thermonuclear designs required validation before a testing ban hardened into custom, and the aborted 1995 test showed that concealment was failing.
8. Status and domestic politics completed it: the BJP's 1998 manifesto promised to induct nuclear weapons, and George Perkovich and Itty Abraham both argue the bomb was as much about postcolonial modernity and recognition as about threat.
9. Multilateralism was not abandoned: a unilateral test moratorium, No First Use and credible minimum deterrence in the 2003 doctrine, then re-entry through the 2008 NSG waiver and the MTCR, Wassenaar and Australia Group memberships.

Conclusion
The shift was overdetermined: a closing window, a deteriorating China-Pakistan nuclear axis, and a government willing to convert capability into status. India crossed the Rubicon to protect an option, not to answer an attack — which is precisely why the question's premise about the absent existential threat is right.
