US-Pakistan pact made him hostile to a plebiscite. Consequently, when the pact was concluded in May 1954, Nehru withdrew the plebiscite offer and declared that the status quo was the only remaining option. Nehru's withdrawal from the plebiscite option came as a major blow to all concerned. Scholars have suggested that India was never seriously intent on holding a plebiscite, and the withdrawal came to signify a vindication of their belief. Indian writer Nirad C. Chaudhuri has observed that Pakistan's acceptance of Western support ensured its survival. He believed that India intended to invade Pakistan twice or thrice during the period 1947–1954. For scholar Wayne Wilcox, Pakistan was able to find external support to counter "Hindu superiority", returning to the group security position of the early 20th century. Sino-Indian War In 1962, troops from the People's Republic of China and India clashed in territory claimed by both. China won a swift victory in the war. Aksai Chin, part of which was under Chinese jurisdiction before the war, remained under Chinese control since then. Another smaller area, the Trans-Karakoram, was demarcated as the Line of Control (LOC) between China and Pakistan, although some of the territory on the Chinese side is claimed by India to be part of Kashmir. The line that separates India from China in this region is known as the "Line of Actual Control". Operation Gibraltar and 1965 Indo-Pakistani war Following its failure to seize Kashmir in 1947, Pakistan supported numerous 'covert cells' in Kashmir using operatives based in its New Delhi embassy. After its military pact with the United States in the 1950s, it intensively studied guerrilla warfare through engagement with the US military. In 1965, it decided that the conditions were ripe for a successful guerilla war in Kashmir. Code named 'Operation Gibraltar', companies were dispatched into Indian-administered Kashmir, the majority of whose members were razakars (volunteers) and mujahideen recruited from Pakistan-administered Kashmir and trained by the Army. These irregular forces were supported by officers and men from the paramilitary Northern Light Infantry and Azad Kashmir Rifles as well as commandos from the Special Services Group. About 30,000 infiltrators are estimated to have been dispatched in August 1965 as part of the 'Operation Gibraltar'. The plan was for the infiltrators to mingle with the local populace and incite them to rebellion. Meanwhile, guerilla warfare would commence, destroying bridges, tunnels and highways, as well as Indian Army
