Tensions have been rising rapidly on the Korean Peninsula over the past few weeks. Military drills involving South Korea, the United States and Japan were met with strong retaliation by North Korea, which has continued through various armed provocations. The situation reached a dangerous new level on Monday morning, when North and South Korean ships exchanged fire.
After a North Korean ship crossed the Northern Limit Line (NLL), the de-facto maritime border between the two Koreas, South Korea’s navy reportedly fired some 20 rounds of warning shots. North Korea, however, claimed a South Korean warship violated the western sea boundary and proceeded to fire 10 artillery shells into the western sea from multiple rocket launchers.
The escalation in tensions began soon after the arrival of the USS Ronald Reagan aircraft carrier at Busan on 23 September. Two days later, North Korea launched its first ballistic missile in what would become a series of military acts, which included an intermediate-range ballistic missile test over Japan, artillery firing drills, fighter jet flight formations, and more.
The moves by North Korea have significantly increased the possibility that the September 2018 inter-Korean military agreement will become obsolete. Under that agreement, made at the time of a spate of summit diplomacy between leaders, the two Koreas decided to create buffer zones on either side of the NLL and to cease all live-fire and maritime manoeuvre exercises within these zones. The goal was to completely suspend all hostile military activity along the inter-Korean border.
However, events seem to be moving in the opposite direction now. South Korea accused the North of violating the military agreement through its recent artillery fire, saying the fate of the deal lies with North Korea.
If the agreement were to be dissolved, it is highly likely that the already tense military situation on the Peninsula would further escalate and turn the inter-Korean border into a volatile zone where accidental clashes could result in a potential all-out military confrontation. Such a scenario would not benefit either North, South, or the wider region. Warning shots could end up killing individuals, a missile could misfire, a ship could be accidentally sunk, a civilian-populated land area could accidentally be hit by a rocket. The possibilities for mistrust to spiral into miscalculation and disaster are frightening.
