According to this enlightening article,
"the regime's main goal is to maintain control of the international highway between the capital and the coast which runs through Homs. This is the only highway left, connecting cities like Tartous and Lattakia – with an 'Alawi majority – and the capital. Regime forces are engaged in deadly fighting in the neighbourhood of Baba Amro in Homs, where opposition fighters have mounted a recent comeback, rather than Raqqa with its strategic importance to the country.
We can conclude from this that the regime priority is to keep control on its supportive cantons rather than keeping Syria whole. We are seeing the partitioning of Syria".
