   Current anchor: armistice, severe unresolved confrontation, and limited de-escalation

   The 1953 Armistice remains the military framework and no peace treaty is verified. No active large-scale direct inter-Korean war is established by the cited record. The DPRK continues nuclear and missile development without IAEA inspector access; dialogue remains limited. The ROK is pursuing unilateral tension-reduction and proposed confidence-building, but no restored bilateral military agreement or comprehensive settlement is verified.

   ROK announces a peaceful-coexistence plan including restoration of the September 19 agreement

   The ROK Ministry of Unification announced plans to begin restoring the September 19 military agreement, pursue peaceful DMZ use, discuss transition from armistice to a peace regime, reject absorption-based unification, and develop a “peaceful two-state relationship oriented toward unification.” These are announced ROK objectives, not completed implementation, DPRK consent, or a peace settlement.

   ROK outlines unilateral risk-reduction steps and intent to restore military confidence

   The ROK Ministry of Unification said the Lee administration had suspended loudspeaker broadcasts, sought to stop leaflet launches, expressed regret over a drone incident, strengthened prevention rules, and aimed to restore military confidence. These are ROK acts and policy goals; do not report DPRK acceptance or restoration of the 2018 agreement without evidence.

    DPRK military plan and UN briefing confirm continued nuclear and missile development

    The DPRK's Ninth Party Congress announced a 2026-2030 military-development plan. In April, the UN told the Security Council that ballistic-missile launches and indications of fissile-material production continued amid a tense environment and limited dialogue. Treat planned systems as intent statements, not proof of operational capability; launch counts are time-bounded to the briefing.

    IAEA reports expanding DPRK nuclear activity while emphasizing lack of access

    The IAEA reported indications of expanded enrichment operations at Kangson and Yongbyon, operation of the 5MW(e) reactor and light-water reactor, and indicators consistent with reprocessing. It also stated that inspectors had not been present since April 2009 and that it could not confirm facility status, design, or activity purpose without access. Do not invent a verified stockpile total.

    ROK halts loudspeakers and both sides remove some border broadcast systems

    President Lee Jae Myung ordered ROK loudspeaker broadcasts suspended on 11 June. The ROK later dismantled its propaganda loudspeakers on 4-5 August, and ROK authorities observed partial DPRK dismantlement on 9 August. The ROK also described restraint on anti-DPRK leaflet launches. DPRK statements rejected dialogue. These are unilateral or reciprocal de-escalatory acts, not an agreement or reconciliation.

    DPRK demolishes northern sections of inter-Korean road links

    The DPRK blew up parts of the Gyeongui and Donghae road links north of the MDL after announcing that it would sever roads and railways. The ROK condemned the act as violating inter-Korean agreements. UNC later said the KPA had notified it of the corridor-severance plan to reduce miscalculation. Demolition did not itself equal an attack on the ROK.

    DPRK alleges ROK drone flights over Pyongyang; responsibility remains disputed

    The DPRK alleged that ROK drones entered Pyongyang airspace and distributed leaflets, issued threats, and later announced an investigation result. ROK authorities did not establish a public, agreed factual account at the time. Keep operator, launch point, control, payload, and state responsibility unresolved unless later competent evidence settles them.

    Trash balloons, leaflet disputes, loudspeakers, and full ROK suspension of the CMA escalate border pressure

    The DPRK began repeated launches of balloons carrying waste into the ROK, describing them as retaliation for anti-DPRK leaflets. The ROK fully suspended the 2018 Comprehensive Military Agreement on 4 June and resumed loudspeaker broadcasts on 9 June. Keep civilian leaflet activity, DPRK balloon launches, government decisions, payloads, and damage as separate facts.

    DPRK expands fencing, mine-laying, clearing, and construction in its side of the DMZ

    ROK authorities reported extensive DPRK mine-laying, vegetation clearing, barriers, and road work in northern DMZ areas, along with accidental-risk concerns near the MDL. Later UNC guidance stressed that construction remaining north of the MDL and not introducing prohibited heavy capabilities is not automatically an Armistice violation; alleged crossings require investigation.

    DPRK leadership recasts inter-Korean relations as two hostile states

    Kim Jong Un rejected the prior reunification relationship and described the Koreas as two hostile states, while DPRK bodies associated with inter-Korean dialogue were dismantled and “principal enemy” language intensified.

    DPRK satellite launch triggers suspension and reciprocal abandonment of the 2018 military agreement

    The DPRK launched what it described as a military reconnaissance satellite. The ROK suspended part of the Comprehensive Military Agreement, citing the launch; the DPRK then announced that it would no longer be bound by the agreement and would restore military measures. Record launch, orbit or function, and agreement status separately; each requires its own evidence.

    DPRK demolishes the inter-Korean joint liaison office in Kaesong

    The DPRK demolished the joint liaison office after escalating objections to anti-DPRK leaflet launches from the South. The ROK called the demolition a breach of inter-Korean agreements. The act destroyed a communication institution; it did not by itself terminate the Armistice or begin a new war.

U.S. officials said the sides could not agree on the scope of sanctions relief and nuclear dismantlement; DPRK accounts differed on the proposal. Record the no-deal outcome and attribute each account rather than selecting one as complete fact.

    Pyongyang Declaration and Comprehensive Military Agreement add concrete confidence measures

    The third 2018 inter-Korean summit produced the Pyongyang Joint Declaration and an annexed Comprehensive Military Agreement. Measures included buffer zones, restrictions on selected drills and flights, guard-post steps, JSA demilitarization work, and communication arrangements. Implementation was partial and later reversed; the agreement was not a peace treaty.

The Koreas marched together and formed a joint women's ice-hockey team under IOC arrangements. Sporting cooperation opened a diplomatic channel; it did not itself change the Armistice or nuclear status.

    The DPRK conducted two July launches assessed as ICBMs, a sixth nuclear test on 3 September, and another long-range missile launch in November. Resolutions 2371, 2375, and 2397 tightened sanctions. DPRK descriptions of a thermonuclear device and missile capability remain claims beyond what the resolutions themselves establish.

The DPRK then conducted a third nuclear test on 12 February 2013; resolution 2094 condemned it and expanded sanctions. A satellite objective does not remove the ballistic-technology issue identified by the Council.

Testing demonstrated nuclear-explosive activity but did not by itself prove operational deployment, reliable delivery, or intent to use a weapon.

The DPRK agreed to freeze and ultimately dismantle specified graphite-moderated reactor and related facilities in exchange for energy arrangements and steps toward normalized relations. It was an agreed process, not completed denuclearization.
