Paragraph 58 - Risk Reduction Measures (MAJOR REVISION) ⭐

REV 1 (Para 58): "The Conference underscores that the risk of nuclear war will persist as long as nuclear weapons exist and that nuclear risk reduction measures can not substitute for the efforts aimed at the total elimination of nuclear weapons.

The Conference suggests that such measures could include but not be limited to: regular dialogue on doctrines and arsenals, enhancing relations with a view to enhance mutual trust and predictability, effective crisis communications, enhanced military-to-military engagement, declarations of restraint, notification and data exchange agreements, non-targeting, maintenance of the lowest feasible levels of alert, procedures to increase the time available for decision-making and to allow for de-escalation of crises, and the reinvigoration of transparency and confidence-building measures, without prejudice to national security."

    • Softer language on compliance (from "diplomatic" to "peaceful" means)

  3. Safeguards Architecture:
    • Restructuring of Iran section into separate paras (7-8) with more general opening

    • Removed statement about "recent developments with far reaching implications"
    • Removed specific examples (entanglement of conventional/strategic, interference in comms/C&C)
    • Added forward-looking language on "maximizing potential benefits of emerging technologies"
  6. Security Assurances (Para 60):
    • Significantly softened: removed "effective, universal, unconditional, non-discriminatory, irrevocable"
    • Removed "by all five nuclear-weapon States"
    • Removed "under all circumstances"

KEY PATTERN ANALYSIS

Overall Direction: Rev 2 shows a pattern of:

  • Modulating language downward on some security assurance specificity
  • Separating and softening Iran language (removing direct IAEA Board findings)
  • Broadening frameworks (New START → all NWS engagement)
  • Removing institutional specificity (CD subsidiary body → general recommendations)
  • Adding balancing language (benefits of emerging tech; cooperation between zones; "peaceful means")
  • Restructuring without major substance changes in review process section

The document appears to be moving toward consensus-building language while maintaining core commitments, particularly evident in security assurances, emerging technology discussion, and institutional mechanisms language.
