Why did the United States stop backing the dollar with gold in 1971?

Research question: Why did the United States stop backing the US dollar with gold in 1971?

The records show that Nixon closed the gold window on August 15, 1971, ending the dollar's backing by gold 18. The dollar had become increasingly overvalued in the 1960s due to a negative balance of payments, public debt from the Vietnam War, and monetary inflation by the Federal Reserve 312. By 1971, US gold reserves had fallen to $12 billion, while foreign central banks held more than $50 billion in dollars they could have demanded in gold 14. Pressure peaked in May 1971, when West Germany left Bretton Woods, and in August, when Britain requested $3 billion in gold from Fort Knox 56. Nixon publicly justified the move by blaming international speculators who he said had waged a war against the dollar 10.
