A series of modest, scattered gains by government forces in recent weeks has produced no decisive breakthrough. But the advances have been made in strategically important locations and point to a new level of direction and energy previously unseen in the army’s performance, military analysts, rebels and Syrians close to the government say…

But analysts say there is little doubt that the pendulum is now swinging in favor of Assad, potentially putting him in a strong position to set terms if the negotiations with the opposition that the Obama administration and Russia last week agreed to sponsor eventually take place.

“If things continue as they are, the government will certainly be the party that has the major advantage” in any talks, said Charles Lister of the London-based IHS Jane’s Terrorism and Insurgency Center. “If we press pause on where we are today, it is clear the insurgency does not pose an existential threat to the regime.”

Pro-Assad analysts credit a major restructuring of government forces that has better equipped them to confront the insurgency. The ranks of the conventional Syrian army — weary, depleted and demoralized by defections, casualties and more than a year of continuous fighting — are being swelled by the deployment of some 60,000 militia irregulars trained at least in part by Hezbollah and Iranian advisers.
