Easier to extract the oil.. then in 20 years build the reactors etc... that being said electric transport will change everything. Oil rich countries need to diversify. That they maintain investments in western countries means that the west can use their countries for military and political dominance in the region.

Oil is cheap not sur why or if it is political. The Middle East might want to prevent tar sand etc... nato might want to destabilize Russia. Venezuela might be an outlier... I'm not sure why it's seemingly ignored.
