Following the attempted Pakistani nuclear attacks on India, China withdrew all official support of Pakistan, and Islamabad fell shortly thereafter. The international community was quick to the scene, and forces from all around the world were quick to condemn the actions of the Pakistani government and stage forces in Pakistan.
The UN has started negotiations between the victorious Indian forces and defeated Pakistanis, with the United States pushing for large concessions from Pakistan to bolster a damaged India. China strongly stands against having a new superpower to their southwest. They have attempted to negotiate a status quo ante bellum with reparations, but the Indians are not interested in it. It seems most likely that Pakistan will pay reparations, disarm its nuclear program, and cede Kashmir to India. This undoubtedly will bring years of insurgency and subversive activities by both sides.
The conflict has shaped future politics in the East and the world as a whole. An emboldened and hardened India, backed by the United States, will provide a formidable challenge to China's dominance in Asia.
