Operation Euphrates Shield, which was launched by Turkey on Aug. 24, established that everything the world was told about the Syrian civil war since 2014 was wrong. The Turkish-backed Free Syrian Army (FSA) forces not only liberated Jarablus, a crucial DAESH stronghold at the Turkish border, but also proved that thousands of lives could have been saved had ground troops been committed early on. Moving forward, the international coalition must adapt to the new reality and part ways with the poorly-conceived plan of fighting terrorism with terrorism.In recent weeks, the Turkish-backed FSA forces accomplished more than most coalition allies did in two years. By liberating Jarablus from DAESH and removing the terrorists from NATO's southeastern border, Turkey proved that the problem would have been fixed if only the coalition was willing to put boots on the ground.Since 2014, however, due to Obama administration's isolationist Syrian policy, the U.S. relied on YPG, the PKK terrorist group's Syrian franchise, in an effort to shrink the U.S. footprint in the Middle East. YPG forces received air support from the U.S.-led coalition along with weapons, ammunition and military advisors. The YPG is basically a terrorist group with almost no local support and ulterior motives, which has been the main problem in U.S.'s alliance with it, along with the group's focus on public relations stunts while neglecting the fight DAESH. As a matter of fact, they paid lip service to the anti-DAESH campaign, while furthering their own secret agenda to carve out a PKK-controlled piece of land in Northern Syria. In the end, YPG overstepped the limits of not only their military capabilities but also demographic boundaries.The YPG's limited capabilities also spelled doom for the U.S.-led international coalition. Although the White House likes to tell the American people that they are making progress, the truth is that the international coalition has proved ineffective in the fight against DAESH. U.S. President Barack Obama's YPG gamble has been such a disappointment that, if U.S. Envoy Brett McGurk was not a government employee, he would have lost his job back in 2015.Now, the international coalition must adapt to the new realities on the ground.The Turkish forces showcased their skills and proved capable of defeating DAESH for good. The Turkish-backed ground incursion marks a turning point in the anti-DAESH campaign. For years, Turkey was falsely accused of refusing to fight DAESH. Now that we have proven critics wrong, it is time to see whether or not our coalition allies mean business. Despite our eagerness to advance, however, the government should not agree to leading to the international coalition's ground force in Syria unless some kind of concrete agreement is reached about the future of Syria.Fighting DAESH with the PKK, the United States merely brought DAESH to a halt. Mr. Obama could not deliver his promise to degrade and defeat DAESH. Meanwhile, countries like Turkey were stalled with confused U.S. policies over what to do with Bashar Assad and how to extricate itself from the Middle East. This confusion has resulted in the Pentagon, CIA and the State Department to fight amongst themselves, creating an environment where each are supporting a different side in the Syrian War, forcing U.S. allies in the region to formulate their own strategies rather than forge a united stance.Ankara's message to Washington is clear: Let's forget about the time when you thought a bunch of terrorists could defeat DAESH. It is time to part ways with the YPG and concentrate on the task at hand.
