SIACHEN, a snowy wasteland at 20,000 feet, has long-term strategic value. Pakistan claims the area west of NJ 9842—the last demarcated point on the LOC—to the Kara -koram Pass. In '84 India put its forces up there. Now these forces are sitting well west of Siachen glacier on the Saltoro ridge. Beyond NJ 9842, the LOC hasn't been defined. Pakistan claims the LOC runs north-east from NJ 9842 straight to Karakoram Pass. India refutes this. The original Karachi agreement of July 1949—which defined the ceasefire line, called LOC after the Simla pact—has the line running north, along Saltoro. In late '92, India and Pakistan had agreed to disengage and redeploy troops and maintain peace.
