The nuclear-armed rivals, which both claim Kashmir and administer separate parts of it, are at a dangerous crossroad after Tuesday’s militant attack, analysts said.

Foremost among these actions is the suspension of the Indus Waters Treaty of 1960, effective immediately, pending what Pakistan's verifiable cessation of support for terrorist activities against India. The treaty guides cooperation on number of cross-border rivers.
