Daniel Levy at Prospects for Peace parses all the possible interpretations of the cross-border strike into Syria so I don’t have to. What’s most striking, though, is that even someone as seriously plugged in as Levy ends up reading tea leaves. But it makes for some interesting speculation.
Since he wrote that post, I’ve seen reports that Syria had withdrawn troops from the Iraqi border, basically curtailing whatever security cooperation they had been extending. But according to Voice of America, not only have the Syrians denied that, they also seem to be taking a pretty measured and even conciliatory stance with regard to the Iraqi government.
