For that justification to be true the timing is odd, as while there is still some fighting in the Syrian Golan it seems to have slowed down in the past several weeks, and no indication that the fighting is about to escalate there.
If anything, Syria’s civil war seems to be turning northward, with the battles mostly centering on the city of Homs and the northern Aleppo Province. Though both rebels and government remain in Golan, they seem to have stalemated and no villages have reported changing hands in quite some time.
