As long as USA kiss their ass for oil, Saudis can do whatever they want. If any other country in area do something like that, hell would open on them.
Not for long .nature will beat the crap out of saudis with their pants down .
Their budget deficit for the year 2015 was around $98 billion. At this rate, their reserves will be gone in just 8 years. Can you believe it? Almost 100 years of wealth accumulated from the oil deposits, blown away in just 8 years. After that, the Saudis will be of no use to anyone. Other than crude oil, they don't have any other resources.
