This morning I came across a Stratfor analysis.
Two brief excerpts:

“This influence, especially among Sunni locals in not just Iraq but also Syria, will be critical if Turkey is going to be able to manage the jihadist threat long after the United States declares mission accomplished and moves on.”
“Not only does Turkey feel that it will have to deal with the mess in Syria long after other stakeholders have moved on, it also knows that the United States expects Turkey to manage the Syrians as well as other regional matters. Turkey has not forgotten how, during the days of President Turgut Ozal, Ankara cut Iraq’s export pipeline in 1990 at the behest of the United States in the run-up to the 1991 Gulf War but was later left with the aftermath as promises of aid disappeared with the subsequent change of U.S. administrations. This bitter experience informed Turkey’s 2003 decision to refuse Washington access to Turkish territory for a northern invasion of Iraq. At the same time Turkey is deeply worried about being caught between Saudi Arabia and Iran, who are engaged in a vicious proxy sectarian war.”

Am I wrong in detecting here a fresh understanding?
About the need for genuine effort to tie all loose ends that were caused while solving a problem before declaring that problem solved?

You can read the whole article here, it is well worth the effort:
