Efforts by Saudi Arabia and Syrian opposition leaders to convince the organisation to back a US military strike failed. Egypt, Iraq, Lebanon, Tunisia and Algeria voiced opposition to foreign military intervention.
Mr Obama had hoped the organisation would endorse language that could back a military operation without the approval of the UN Security Council. But the Arab world remains starkly divided on Syria and hostile to further US-led wars in the region despite widespread public sympathy for Mr Assad’s opponents.
We can act unilaterally, but I suspect it won't accomplish much if we don't get support from the regional actors. In fact it would be better for an Arab country to take the lead and we support, but the odds of that happening are politely very slim.
