U.S. 'success' in Middle East has only created more problems

Iraqis shout as they carry the coffin of a victim following a twin suicide bombing attack, claimed by the Islamic State (IS) group, in the southern Iraqi city of Samawah, situated deep in Iraq's Shiite heartland, on May 1, 2016.

(CNN)Iraq is collapsing as a country. This week's bombings in Baghdad, which killed more than 90 people, are just further reminders that the place remains deeply unstable and violent. There is a lesson to be drawn from this, one that many powerful people in Washington are still resisting.

As Iraq has spiraled downward, policymakers have been quick to provide advice. Perennial hawks such as Sen. John McCain (R-Ariz.) have argued that if only the Obama administration would send more troops to the region, it would be more stable. Others say we need more diplomats and political advisers who can buttress military efforts. Still others tell us to focus on Iraqi leaders and get them to be more inclusive.
Perhaps it is worth stepping back from Iraq and looking at another country where the United States has been involved.
