In the Arabian Sea, two warships — one Pakistani, one Indian — made physical contact in waters both nations claim the right to patrol, marking a rare and consequential shift in how one of the world's most fraught rivalries expresses itself. Where decades of tension between these nuclear-armed neighbors has largely unfolded on land or through diplomatic channels, the sea now carries the weight of that unresolved history. A collision is not a declaration, but it is not nothing either — it is the kind of event that reminds the world how quickly proximity becomes peril when mistrust runs deep.
