In Thomas Friedman's interesting sit-down with Obama about the Iran deal, this tidbit on US policy towards Arab countries:
Regarding America’s Sunni Arab allies, Obama reiterated that while he is prepared to help increase their military capabilities they also need to increase their willingness to commit their ground troops to solving regional problems.
“The conversations I want to have with the Gulf countries is, first and foremost, how do they build more effective defense capabilities,” the president said. “I think when you look at what happens in Syria, for example, there’s been a great desire for the United States to get in there and do something. But the question is: Why is it that we can’t have Arabs fighting [against] the terrible human rights abuses that have been perpetrated, or fighting against what Assad has done? I also think that I can send a message to them about the U.S.’s commitments to work with them and ensure that they are not invaded from the outside, and that perhaps will ease some of their concerns and allow them to have a more fruitful conversation with the Iranians. What I can’t do, though, is commit to dealing with some of these internal issues that they have without them making some changes that are more responsive to their people.”
One way to think about it, Obama continued, “is [that] when it comes to external aggression, I think we’re going to be there for our [Arab] friends — and I want to see how we can formalize that a little bit more than we currently have, and also help build their capacity so that they feel more confident about their ability to protect themselves from external aggression.” But, he repeated, “The biggest threats that they face may not be coming from Iran invading. It’s going to be from dissatisfaction inside their own countries. Now disentangling that from real terrorist activity inside their country, how we sort that out, how we engage in the counterterrorism cooperation that’s been so important to our own security — without automatically legitimizing or validating whatever repressive tactics they may employ — I think that’s a tough conversation to have, but it’s one that we have to have.”
Let me translate that for you: our priority in the Arab world is selling them weapons and making sure that the regimes are stable enough so that they will keep buying our weapons, and don't act too embarrassingly either in terms of human rights and so on because it might make selling them weapons more difficult. Also, we would like to formalize as much as we can how we will sell them weapons.
