Why India and Pakistan have spent decades fighting over a frozen, uninhabited mountain wasteland

In short: Known as the world's most elevated combat zone, the Siachen Glacier has been a site of intermittent warfare since 1984. Despite the region being largely barren and inaccessible, both nations maintain thousands of troops at altitudes exceeding 6,000 meters, enduring extreme weather and natural hazards in a costly, decades-long standoff.

The conflict originated from a cartographic ambiguity following the 1949 Karachi Agreement and the 1972 Simla Agreement. These treaties demarcated a ceasefire line ending at a coordinate known as NJ9842, but the text vaguely extended the boundary 'thence north to the glaciers.' Because this remote, high-altitude terrain was considered worthless, officials did not clearly define control. However, by the late 1970s, mountaineering expeditions—often permitted by Pakistan—began signaling territorial claims, prompting India to launch its own reconnaissance and climbing missions to assert sovereignty.

In April 1984, India launched Operation Meghdoot to preemptively occupy the Saltoro Ridge and key passes like Sia La and Bilafond La. This move effectively secured the high ground for India, forcing Pakistani forces to hold lower positions on the western slopes. The strategic advantage of the ridgeline has remained with India ever since. Subsequent years saw numerous attempts by Pakistan to reclaim these heights, including the 1987 Operation Qaidat and various skirmishes throughout the 1990s, yet the front line—now called the Actual Ground Position Line—has remained largely static.

The human and economic toll of the conflict is immense. Since 1984, over 2,000 soldiers have perished, with the vast majority succumbing to avalanches, frostbite, and altitude sickness rather than direct combat. Both nations maintain roughly 150 outposts, with annual maintenance costs reaching hundreds of millions of dollars. Despite a 2003 ceasefire, the region remains a symbol of deep-seated mistrust. For Pakistan, the loss of territory is viewed as a significant military humiliation, while for India, the occupation of the Saltoro Ridge represents a vital, if grueling, defense of its perceived borders.
