Great to Know

It demonstrated that Pakistan’s two wings, separated by over a thousand miles of Indian territory, could not be held together purely through central military and political control.
• India’s decisive military success in 1971 is often cited as a turning point in India’s regional strategic standing and self-confidence during this period. This stood in contrast to the more difficult outcome of the 1965 war.
