“Yes, speculators are a part of supply and demand. So what?”
So when a Saudi prince has a bad case of acne, speculators drive the price up.
How?
In addition, if the Wahhabist Saudis (OPEC's #1 energy exporter)were not earning billions of $$$ off the Western customers, they would be unable to bankroll Sunni related terrorism around the world. Iran (opec #2 exporter) bankrolls Shia related terrorism - worldwide. Hopefully Tehran's Shi'ite terrorism exporters won't be in business much longer.
If the leading Islamic 'oil-jihad-banks' had the 'blood of Allah' removed, global Islamic related terrorism would drop considerably.
