For the last 60 years or so, the relationship between the US and the Gulf states can be likened to a Catholic marriage. Both were in need of each other and kept supporting each other in times of difficulty. During the oil crisis, the Gulf states came to the help of the world economy by pumping more oil into the market. As a result, the world economy stabilised, including the US market.
Similarly, at the time of security threats in or around the Gulf, the US was ready to support softly through diplomacy on the world arena, or if needed even by force. The US needs a steady flow of relatively cheap oil to its allied markets and the Gulf states need security. That is what made diplomats and politicians describe this relationship as a — hard to end — Catholic marriage. However, things have changed recently and taken a new turn.
