Tuesday's bloodshed in Pahalgam - where at least 26 tourists were killed in a hail of gunfire - marks the deadliest militant attack in Indian-administered Kashmir since 2019.The victims weren't soldiers or officials, but civilians on holiday in one of India's most picturesque valleys. That alone makes this strike both brutal and symbolic: a calculated assault not just on lives, but on a fragile sense of normalcy the Indian state has worked hard to project in the disputed region.Given the fraught history of Kashmir - claimed in full by both India and Pakistan but ruled by each only in part - India's response is likely to be shaped as much by precedent as by pressure, say experts.For starters, Delhi has swiftly taken a series of retaliatory steps: closing the main border crossing, suspending a critical water-sharing treaty, and expelling diplomats.
