Well , the one above is wrong . i n d iapakistanwarroleofrussia . htmlThe planned action plan for Pakistan was to attack on 4 sides as India had no ally at that time . Due to Soviet Treaty , China backed out and once Russia came in Bay of Bengal destroying Britist forces , US backed out . Rather than getting advantages of its strategic alliances , Pakistan failed as USSR was quicker . Nuclear Submarines are a powerful force . Once US pulled out and China avoided any attack , Pakistan was always bound to lose . India enjoys strategic advantage over Pakistan when Bangladesh then East Pakistan comes . And in Kashmir , India still has a larger army and is a larger state . Larger states are usually far stronger . See , India vs China , China wipes the floor .
