WASHINGTON, Sept 14 : US presidents are just as likely to be remembered for their foreign policy failures as their successes.
Jimmy Carter sealed the Camp David accords, bringing peace between Israel and Egypt, but his presidency wilted with every passing day of the Iran hostage crisis.
Bill Clinton failed to stop the horrors of Rwanda's genocide and George W. Bush will forever be remembered as the president who took the United States to a costly war in Iraq.
Barack Obama, the 44th president, has strived for a legacy-gilding nuclear deal with Iran, unfrozen relations with Cuba, pivoted to Asia and hunted down Osama bin Laden.
But he may ultimately be remembered for his failure to stop a humanitarian catastrophe in Syria.
In just over four years, the conflict has killed more than 240,000 people and prompted the most serious refugee crisis since World War II.
From the blood-stained rock and sand has seeped a miasma of jihadist groups -- from Al-Qaeda and the Islamic State.
In many ways, the Syrian problem has been the perfect foreign policy storm for Obama.
He came to office determined to end the perceived hubris of his predecessor. ?AFP
