Referring to the spread of the Daesh (ISIL) terrorist group in Syria and Iraq, Obama promised to work with the international community because the US cannot resolve world problems by itself.
"No matter how powerful our military, how strong our economy, we understand the United States cannot solve the world's problems alone," Obama said. "In Iraq the US learned the hard lesson that even hundreds of thousands of brave troops, trillions of dollars... cannot itself impose stability on a foreign land."
"The United States is prepared to work with any nation, including Russia and Iran, to resolve the conflict," Obama said at the annual gathering of world leaders, according to media reports.
"But we must recognize that there cannot be, after so much bloodshed, so much carnage, a return to the pre-war status quo,” he added.
“If we cannot work together more effectively, we will all suffer the consequences,” Obama warned his fellow world leaders. “That is true for the United States as well. No matter how powerful our military, how strong our economy, we understand: The United States cannot solve the world’s problems alone.”
Syria has been gripped by civil war since March 2011 when terrorists backed by the US and its allies began their deadly campaign in the country.
In the past four years, more than 240,000 people have died in Syria -overwhelmingly civilians– and around 4 million Syrian people are now refugees in other countries. Another 7.6 million are displaced inside the Arab country.
