While speculation continues about whether Turkey and Saudi Arabia will march into the Syrian war, Turkey is already fighting on two fronts without even entering Syria.
In the first, Turkey is launching heavy artillery fire at Syrian Democratic Forces advancing toward Azaz in northwestern Syria, while declaring that the objective is to stop the advances of the Kurdish People's Protection Units (YPG). On the second front, Turkey is allowing militants to cross into Syria, since the Syrian army cut off the Aleppo-Kilis corridor.
