Two Navies, One Collision, Two Entirely Opposite Official Stories - What the 3-Nautical-Mile Rule Actually Settles

THE ONE RULE BOTH GOVERNMENTS' STATEMENTS SECRETLY AGREE ON

India and Pakistan disagree about almost everything in this incident - who provoked whom, whose waters it happened in, whose ship was at fault. What neither side disputes is the 3-nautical-mile rule itself. That silent agreement on the yardstick, even amid total disagreement on the facts, is the real story here.

WHAT EACH SIDE IS ACTUALLY PROTECTING

India's statement is built to do two things at once: assert a rules-based violation (Article 10, COLREGs) rather than just trade accusations and downplay damage to project that its frontline destroyer was unaffected and remains operational.

Pakistan's statement is built to protect something different - a domestic narrative around its biennial SEA-SPARK exercise, framing the incident as Indian aggression inside its EEZ rather than acknowledging a smaller patrol vessel's manoeuvring error.

Neither government is lying about the collision happening; each is choosing which established framework - bilateral CBM law versus EEZ sovereignty - better protects its own position.

WHY THE TONNAGE GAP MATTERS MORE THAN THE RHETORIC A

7,400-tonne destroyer and a 2,600-tonne patrol vessel colliding is not symmetrical by physics, whatever the diplomatic language claims. India's account - a smaller, faster vessel closing in and attempting a "dangerous overtaking manoeuvre"

• is consistent with the size mismatch in a way Pakistan's "aggressive Indian manoeuvres" framing has to work harder to explain. This is not proof of intent, but it is exactly the kind of detail dueling official statements are designed to obscure rather than surface.

WHAT THIS ACTUALLY REVEALS ABOUT CBM ARCHITECTURE

The 1991 Advance Notice Agreement was built to prevent tactical incidents from becoming strategic crises - and on that narrow test, it has worked: both sides summoned diplomats, not warships. But the agreement's real weakness isn't enforcement of the 3-nautical-mile rule; it's that it has no mechanism for establishing whose account of a violation is accurate.

It can catch that ships got too close. It cannot adjudicate why. That gap between what a CBM can verify and what it can settle is precisely why the two statements can both invoke the same 1991 agreement and still arrive at opposite conclusions - a structural fragility worth understanding well beyond this one incident.
