A time comes in the course of deadly upheavals when the world wearies and the bloodshed turns routine.
Syria's Bashar Assad bet it would unfold that way. From the beginning of this struggle, he warned his country that the foreign cavalry would not show up, that the promises of help will not materialize. The world is feckless, despots know, and all they need to do is to hunker down and wait out the initial moment of outrage.
Indeed, Bashar had the better coalition on his side. The friends of the Syrian regime — the Hezbollah militia in Lebanon, the Iranians, the Russians and to some extent the sectarian Shiite government in Baghdad — enabled the dictator to hold on and reverse the course of battle.
Meanwhile, the Western democracies, the Sunni Arab states and Turkey have run out the clock on the Syrian people.
The cavalry was always on the way, just another massacre away; the weapons supplies were in the pipeline, and the commitment to break the back of the Damascus regime just around the corner.
President Obama was politically shrewd about Syria. There was no great campaign for intervention in that country's bloodshed, no "progressives" were appalled by the violence, and Republicans in the House and Senate were equally indifferent. Sure, there was Sen. John McCain, relentless and offended by the violence, insisting that the unraveling of Syria carries consequences for American security, but he was a voice in the wilderness.
The Obama administration never grappled with the reality of Syria. It looked at Syria and thought and spoke of Iraq. We were war weary, Obama said, over and over. There were sectarian terrors in Iraq, and they would be waiting for us in Syria as well. We would find no gratitude in Aleppo and Hama.
The beards came to the rescue of American policy. Those Islamists, the jihadists who made their way to Syria, were a solution to the moral embarrassment. That we could not be on the side of al-Qaida's Ayman Zawahiri was one of the more memorable formulations of then Secretary of State Hillary Clinton. She served her president's interests fully during her tenure. She kept Syria from intruding into his bid for a second term.
