In all India-Pakistani crises, the major powers, especially the United States, seek to prevent the breakout of armed conflict and, if that occurs, achieve earliest ceasefire between the two countries.
This has been particularly the case since India and Pakistan carried out nuclear tests in 1998. It was witnessed during the Kargil conflict, the Mumbai terrorist attack of 2008 (when India chose the diplomatic route), and the Balakot aerial strikes of 2019. In all these instances, the US maintained contact with both sides and, after the crisis was over, hinted at the role it had played, but went no further.
This has not been the case in the ceasefire that was agreed upon between the Directors General of Military Operations (DGMOs) of India and Pakistan on 10 May to stop armed action following the launch of Operation Sindoor by India in the early hours of 7 May.
