Declassified documents
According to the recently declassified official documents, the US policy tilt towards Pakistan during the 1971 war extended beyond political rhetoric.
Dictated by a congressional decision, the US government was prohibited from providing any military assistance to the warring parties. Records show that military aid was directed to Pakistan through other sources. These papers reveal how President Nixon and Henry Kissinger sided with Pakistan in the UN sessions and condemned Indian government policies, even though their media was painting a very negative picture of the Pakistan armed forces.
The most interesting part relates to the transfer of military hardware. 3-F5 and 11-F104 fighter planes were routed to Pakistan via Tehran and Amman, Jordan. China was also encouraged to support Pakistan through all means possible and was given assurance of the US governmental support in case the USSR intervened on behalf of India. The much-discredited Seventh Fleet was moved into the Indian waters as a clear warning sign to the Indian government.
Even though these important historical facts will not be popular or appreciated in times like these, it is equally important for Pakistanis to know their correct history rather than the usual propaganda dished out by self-serving pied piper political pundits.
