Do I need any, to doubt an insane estimate like $2B? If I said I saw a 12-ft tall gorilla at the carnival, would you want another figure, or just conclude it's FAR more likely I was wrong?
We're talking about TWO BILLION dollars. Statements like that are extraordinary and require proof.
The 2 Billion number has come from the India Press. The WH denies it but refuses to name a number itself.
