Claim

Nehru made a mistake by signing an unequal treaty (the Indus Waters Treaty) in 1960, giving Pakistan 80% of the Indus river system's waters and additionally paying Pakistan compensation to help build its water infrastructure.

“न्यू ने 1960 में एक असमान समझौते पर हस्ताक्षर करके गलती की थी। ... न्यू ने औद्योगिक जल प्रणाली का 80% हिस्सा पाकिस्तान को दे दिया है और न्यू ने पाकिस्तानियों को बुनियादी ढांचे के निर्माण में मदद करने के लिए मुआवजा भी दिया है।”

Rationale

The three specific, verifiable factual assertions are all correct: (1) Nehru signed the Indus Waters Treaty in 1960; (2) it allocated the three Western Rivers — roughly 80% of the Indus system's total mean annual flow — to Pakistan while India retained ~20% via the three Eastern Rivers; and (3) under Article V, India additionally paid £62.06 million into the Indus Basin Development Fund to help finance Pakistan's replacement canals and dams. The words 'mistake' and 'unequal' are the speaker's opinion, not verifiable facts, and it omits context that the pact was a World Bank-mediated, mutually agreed settlement widely regarded as durable — but every concrete factual figure in the claim checks out against primary sources.
