The agreement has not prevented the relationship between the two countries from deteriorating to the point of armed conflict, most recently in the Kargil War of 1999. In Operation Meghdoot of 1984 India seized all of the inhospitable Siachen Glacier region where the frontier had been clearly not defined in the agreement (possibly as the area was thought too barren to be controversial); this was considered as a violation of the Simla Agreement by Pakistan. Most of the subsequent deaths in the Siachen Conflict have been from natural disasters, e.g. avalanches in 2010, 2012, and 2016.
