You are joking, right? The president does not know the laws and are therefore exempt from responsibility? The president does not know about a deal he presents himself?
I'm absolutely serious. It's not enough to just prove the cash was given the prosecution then has to show that the party giving the cash has actual knowledge it is to be used in the preparation or actually carrying out of terrorism offences. Good luck. They might be reckless. Or even negligent but that's not knowledge.
