Despite the Obama administration's predictions that the Syrian government's days are numbered, recent U.S. intelligence reports suggest President Bashar Assad commands a formidable army that is unlikely to turn on him, an inner circle that has stayed loyal and an elite class that still supports his rule.

The assessment hinted at a continuing campaign lasting several months, if not longer, with more Syrians dying. For the past year, Assad's government has tried to crush a popular uprising inspired by the Arab Spring movements. The U.N. says more than 7,500 people have died.

Over time, worsening economic conditions could threaten Assad's hold on power. Food prices recently doubled, unemployment is rising and refined fuel products are running out.

But no mass protests over food or fuel shortages have broken out, and there hasn't been any discernible slowing in military activity because of a lack of supplies, three senior intelligence officials said Friday. They spoke on condition of anonymity to provide a snapshot of recent intelligence reports and analysis of the crisis.
