It didn't do it in Libya and are even more unlikely to do so in Syria.
From a military perspective Assad needs to worry more about Turkey. Until recently Turkish PM Erdogan was Assad's best buddy but no more.
"Meanwhile, Turkey said it would begin military maneuvers along its border with Syria this week. Though previously announced, the location of the exercise near the border seemed a move by an
increasingly assertive Turkey to bring more pressure on Damascus.
“Now they’re really banging the gavel,” an Obama administration official said of the Turkish announcement. “They’re suddenly moving very fast.”
"Turkey remains a wild card in the developments in Syria.
Prime Minister Recep Tayyip Erdogan, once one of Mr. Assad’s closest allies, has said he will no longer communicate with the Syrian president, after Mr. Assad repeatedly misled Mr. Erdogan and other Turkish officials about his intentions. Turkish officials have said they will impose sanctions soon, possibly by this week, potentially deepening Syria’s economic woes. Particularly in Aleppo, near the Turkish border, Turkey has fostered economic ties."

a move that had sent prices soaring and provoked outrage among a business elite that has until now backed the leadership of President Bashar al-Assad in his nearly seven-month contest with anti-government activists.""Analysts said that the ban imposed last week on imported merchandise, which included cars, household appliances and even food items, underscored a deep sense of anxiety among the authorities as Syria faces some of its most dangerous political unrest in four decades of dictatorship. Officials said it was needed to protect foreign currency reserves.
Analysts said the ban had been ordered without any study of the potential effects on the Syrian market or on Syria’s trade agreements with neighboring countries. Some economists in Syria said
the import ban and its reversal were indicators that the Syrian leadership remained uncertain in the face of the uprising and its ramifications for the Syrian economy."
