The strike won't last. Everybody is sniping at oil while being fully aware that oil is the economic lifeblood of the entire planet. Don't get in the way of oil, you won't even be a footnote in history.
I broker Nigerian Bonny Light Crude Oil on a daily basis. The strike probably won't last long but I will say that Shell has been screwing the Nigerians for years. It's time the Nigerian government toss Shell out on their collective butts.
"oil is the economic lifeblood of the entire planet."
Yes it is, and a good thing. Being traded on global markets, it means no country of consequence(such as China, e.g.) has anything to gain by instability or runaway prices.
Which also means, any producer country with delusions of grandeur will be without powerful friends but have several powerful antagonists.
