This is the supposed “smoking gun” presented by the Americans as proof of a conspiracy to provide hundreds of millions to Iran. From The South China Morning Post. SCMP has the other 16 slides, an ordinary, dull corporate presentation that says very little.
I am not a lawyer. It appears to be very weak evidence that would prove little in an unbiased courtroom. It was ridiculous to make an international incident out of it.
On the other hand, U.S. law allows prosecutions for “conspiracy” and other “crimes” on very little evidence. It was designed to prosecute the Mafia but now is used in many other areas.
