Last year I obtained 2 papers regarding International Terrorism – as differentiated from Domestic – with one coming from the US State Department and the other having been done by an academic from Chicago.
When looked at, the paper from Chicago turned out to be almost 99% blank. The State department, 5 pages, outlined how, at a certain level, the terrorists were all working together and sharing resources. So that’s IRA with Sandinista’s, or Islamic State, or Noriega with Cocaine money. At a “certain” level it may appear as if the exact same “players” are behind all the “events” on your radar. [It’s because they “actually” hold meetings of their “tribes” or “clans” — or did in the 70s, 80s etc]
It’s similar to what writers have had to say about Scientology.
