Washington is now forced to look on in horror as the so-called "moderate" rebels have joined al-Qaeda’s Syrian branch and as violence escalates following the collapse of the ceasefire.
Meanwhile, collapse of the Syrian ceasefire, aimed at US-Russian cooperation on airstrikes against Islamic State and al-Qaeda, is going to leave a worsening conflict to US President Barack Obama's successor. "As his presidency comes to a close, the fact is that Obama has little to show the world on Syria. With an estimated half a million deaths, the Middle East in flames and European allies destabilized by the impact of refugee flows, he will pass on a festering crisis to his successor," the Guardian reported Thursday.
Frederic Hof, a former Obama adviser on Syria who is now at the Atlantic Council think tank, said "For the next president on Day One, this becomes the problem from hell. It's a problem that's going to persist in one way or another throughout the first term of the next president and probably beyond."
In the Syrian conflict Obama has chosen to follow a line of containing the conflict rather than solving it. As a result, US-backed rebels became disillusioned with American policy and began joining al-Qaeda's Syrian branch.
