The Mossad is Israel's intelligence agency.
Ehud Barak is a former head of the Mossad. The Mossad sets up intelligence operations to benefit Israel, such as Mossad Blackmail Ring s. It is standard procedure for intelligence agencies, such as the Mossad or the CIA to use middle men, so they have plausible deniability. The Mossad are notorious for utilizing mafia connections as fronts for their operations. Israel cannot be caught giving money directly to terrorist groups like Al Qaeda, drug cartels, and ISIS, so they use middle men, intermediaries, to do it.
