It was actuyally a "money walking" scheme (similar to the gun walking scheme) where the idea was to watch where the money went.   It went almost immediately and almost in entirety to Hezbolha and many of the Islamic militias (both Suni and shia)    much of the moneys went through the hands of the revolutionary guards into the war front....   Takeaway.   Most of the moneys went into financing terror that then killed jews (rockets), the war in yemen and against western soldiers.
