Turkey continues shelling inside Syria - war already on, how long before NATO moves in?

Editor's Note: With civil war raging inside its own borders, Syria cannot possibly want to launch a war against a more powerful neighbor, Turkey, that is supported by the greatest military force the world has ever known, namely the US / NATO forces. So it would appear to me that the aggressor in this case has to be Turkey, that is launching a proxy war against Syria on the behest of US / NATO Western military interests. BIG WARS HAVE SMALL BEGINNINGS, and like World War 1 that erupted from a minor incident, it appears that this conflagration can easily erupt into something much bigger, World War 3, for instance!

Turkey retaliates at Syria for a fifth day — RT

Turkey has returned artillery fire at Syria for a fifth consecutive day, after mortar from Syria landed in the Turkish border town of Akcakale. The shell landed some 200 meters inside Turkey, AP reported. According to Reuters, it hit near a plant belonging to the Turkish Grain board, several hundred meters away from the city center.

A short time later, at least six mortars could be heard fired from Turkey. Abdulhakim Ayhan, the mayor of Akcakale, confirmed that Turkish artillery immediately returned fire. No casualties have been reported. It's the latest move in the already tense relationship between the neighboring countries.

The crisis began on Wednesday, when Syrian mortar shells killed a woman and four children from the same family in Akcakale. The shells also wounded at least 13 people. The incident triggered artillery strikes by neighboring Turkey. Ankara has deployed additional troops to its southern border with Syria.
