Doubtful, says the ever insightful Michael Koplow:
The [Turkish] government needs to be seen as strong when Turkish blood is spilled, but Erdoğan is also playing this game very exactly, since there is a fine line between taking limited action that conveys strength and resolve and getting drawn into a tactical mess in Syria.
What I expect will happen is another round of strong condemnations, more strident threats to intervene in Syria, mobilizing tanks, artillery, planes, and troops to the border…and ultimately Turkey will stay on its own side of the line. As I keep on reiterating, Turkey is in a lose-lose situation when it comes to Syria without a good answer at hand, and yesterday’s events reinforce that even further. The bottom line though is that given the constraints involved, it is going to take a lot more than shelling a border town to start a real war between Turkey and Syria.
