The Atlantic piece on the Obama doctrine has some interesting information:
In 2014, after she left office, Clinton told me that “the failure to help build up a credible fighting force of the people who were the originators of the protests against Assad … left a big vacuum, which the jihadists have now filled.”
The king of Jordan, Abdullah II—already dismayed by what he saw as Obama’s illogical desire to distance the U.S. from its traditional Sunni Arab allies and create a new alliance with Iran, Assad’s Shia sponsor—complained privately, “I think I believe in American power more than Obama does.” The Saudis, too, were infuriated. They had never trusted Obama—he had, long before he became president, referred to them as a “so-called ally” of the U.S. “Iran is the new great power of the Middle East, and the U.S. is the old,” Jubeir, the Saudi ambassador in Washington, told his superiors in Riyadh.
“Assad is effectively being rewarded for the use of chemical weapons, rather than ‘punished’ as originally planned.” Shadi Hamid, a scholar at the Brookings Institution, wrote for The Atlantic at the time. “He has managed to remove the threat of U.S. military action while giving very little up in return.”
One box he called isolationism, which he dismissed out of hand. “The world is ever-shrinking,” he said. “Withdrawal is untenable.” The other boxes he labeled realism, liberal interventionism, and internationalism. “I suppose you could call me a realist in believing we can’t, at any given moment, relieve all the world’s misery,” he said. “We have to choose where we can make a real impact.” He also noted that he was quite obviously an internationalist, devoted as he is to strengthening multilateral organizations and international norms.
In recent days, the president has taken to joking privately, “All I need in the Middle East is a few smart autocrats.” Obama has always had a fondness for pragmatic, emotionally contained technocrats, telling aides, “If only everyone could be like the Scandinavians, this would all be easy.”
“It is literally in my DNA to be suspicious of tribalism,” he told me. “I understand the tribal impulse, and acknowledge the power of tribal division. I’ve been navigating tribal divisions my whole life. In the end, it’s the source of a lot of destructive acts.”
If there had been no Iraq, no Afghanistan, and no Libya, Obama told me, he might be more apt to take risks in Syria. “A president does not make decisions in a vacuum. He does not have a blank slate."
