Even if you think the Kingdom of Saud will explode tomorrow, whatever despot/warlord/theocracy/hippy commune that will arise to replace it will keep pumping that oil out of the sand.
Waiting for Saudi oil to go away is magical thinking.
Don't say that too loud. Trump might get ideas that'll make the 8 years under Bush jr look like a playground spat.
This is wishful thinking
Well thinking that oil will go back up might be but Saudi did this this exact same thing before.
