Saudi Arabia is the first country to decline a seat at the UN Security Council. Ostensibly, it's because they think the UN is pretty useless in solving problems. They fault the US for not supporting the rebels in Syria and for not solving the Palestinian/Israeli stalemate.
The Saudis are known for funding terrorists, and so they wanted the US to support the rebels, which, we've learned, many of whom have ties to A-Q. They were ticked off when Obama decided to negotiate with Assad. They have gripes with Assad because he's friendly to Iran. Not to mention that Obama is also playing nicey-nicey with Iran. So, of course, the Saudi's wouldn't be fond of Putin, either, since he supports Assad.
Meanwhile, another article cites that China now buys as much oil from the Saudis as the US (a change from a decade ago) ... making China a country that the Saudis might find more friendly to their interests than the US.
Basically, the US turned a blind eye to the Saudis' terrorist connections, in return for which the Saudis assured the US their oil supply. The oil-producing countries of the ME surely realize that their oil is no longer quite the factor it was before the new oil & gas production occurring in North America (and even in Europe).
