At the peak of the 1965 Indo-Pak war, the then Prime Minister Lal Bahadur Shastri wrote a letter to US President Lyndon Johnson wherein he informed the American leadership that New Delhi is willing to agree to an unconditional ceasefire.
He in his letter dated September 16, 1965 ruled out plebiscite in Kashmir arguing that the 1948 UN resolution in this regard was no longer acceptable.
Shastri's comments came after the then Pakistan foreign minister Zulfikar Ali Bhutto told Americans that Pakistan was ready to be degraded as a nation but would not give up its claims over Kashmir.
During the conversation, McConaughty told them that Pakistan was responsible for this war, by sending troops inside Kashmir and using American weapons -- which were given for use against a communist China -- against India.
The same day, the Johnson Administration in a separate telegram asked McConaughty to convey a tough message to Pakistan that it should not portray itself as a victim, for which it itself was to be blamed.
"We (are) aware India first put regular forces across CFL but Pak responses thereto in Chhamb area struck at points India considered vital, and Indians have long asserted (a) they could not tolerate continued Pak offensive, and (b) if Pakistan should strike India's vital interests, India would have no choice but to respond in area of its own choosing. GOP must have been well aware of risk involved in its own actions in Jammu and Kashmir," the State Department said.
