National Interest has a wonderful article penned by Paul Pillar titled “How Donald Trump Should Transform America’s Middle East Policy.”
He states the quite obvious that
An immense share of the blood and treasure the United States has lost overseas in the past couple of decades has been in the Middle East, an expenditure that has not brought proportionate benefits.
You can rattle off the failures easily, from the Iraq invasion to the dithering in Syria. Obama’s Pivot to Asia, which was based on an interpretation of America being over-involved in the Middle East, was a good start in addressing our poorly formulated regional policy. Yet, a significant chunk of his foreign policy legacy will be defined by his inability to disentangle America from Middle Eastern politics. This includes Libya, Yemen, Syria, ISIL, Iran, the Arab Awakening, Peace Process, etc..
What is to be done? The US still has interests in the Middle East, but they should be better defined and more limited. Moving forward, his recommendations include
…the initial principle that the new administration should observe in making policy toward the region is the Hippocratic one of first doing no harm. A second principle is to keep costs and risks commensurate with prospective gains to U.S. interests. A third is to recognize that not all problems, even heart-rending ones, are solvable, and that if they are, the United States is not always best suited to solve them. Often the interests and objectives of other players in the region are better engaged, and this sometimes means taking advantage of the balancing of conflicting interests.
Highly recommended that you read the entire thing (quickly as it will soon be gated).
