In the winter of 2014, the United States kept Iran out of a peace conference aimed at beginning talks to end the civil war raging in Syria. There were good reasons for doing so since, as the Obama administration acknowledged at the time, Iran was a belligerent in that conflict. Tehran had deployed elements of its Quds Force as well as its Hezbollah terrorist auxiliaries on the ground in Syria to help the tottering Bashar Assad regime hold power. But more than a year and a half later after that futile gesture at starting negotiations failed, Secretary of State John Kerry came hat in hand to a meeting with Iranian Foreign Minister Mohammad Javad Zarif at the United Nations yesterday to ask that his country join the latest effort to resolve the Syrian catastrophe. Coming on the heels of their triumph in the nuclear talks, this was one more sweet triumph for an Iranian regime that is acknowledged to be the world’s leading state sponsor of terror.
