Carter was weak on foreign policy and Obama is following in his footsteps.
From Spiegel: (Article: ‘Obama’s Middle East Policy Is in Ruins’)
US President Barack Obama’s Middle East policy is in ruins. Like no president before him, he tried to win over the Arab world. After some initial hesitation, he came out clearly on the side of the democratic revolutions. … In this context, he must accept the fact that he has snubbed old close allies such as Israel, Saudi Arabia and the Egyptian military. And now parts of the freed societies are turning against the country which helped bring them into being. Anti-Americanism in the Arab world has even increased to levels greater than in the Bush era. It’s a bitter outcome for Obama.
Obama was naive to believe that one only needed to adopt a new tone and show more respect in order to dispel deep-seated reservations about the free world. In practice, the policies of the Obama administration in the region were not as naive as they may have seemed at times, and the Americans have always been much more involved in the Middle East than the passive Europeans. But Washington has provided the image of a distracted superpower in the process of decline to the societies there. This image of weakness is being exploited by Salafists and al-Qaida, who are active in North Africa from Somalia to Mali.
One thing is clear: If jihadists believe they can attack American installations and kill an ambassador on the anniversary of Sept. 11, then America’s deterrent power has declined considerably. For a superpower, it is not enough just to want to be loved. You have to scare the bad guys to keep them in check.
