Where did $100 billion go?

(UKRINFORM) — Ukraine has received military aid from the United States worth more than $70 billion, but claims that U.S. support has amounted to $100–200 billion are inaccurate, President Volodymyr Zelensky said.
He stated this in an interview with the Associated Press, according to Ukrinform.
“As the president of a country at war, I can say that we have received more than $75 billion [in U.S. aid]. But the claims that Ukraine has received $100 billion out of the $177 billion total, or even $200 billion, as some say, are simply not true. This is important because we are talking about specifics — we did not receive this aid in cash but in weapons. The total value of the weapons we received is just over $70 billion,” Zelensky said.
