"I think Mr. Putin understands that ... with Afghanistan fresh in the memory, for him to simply get bogged down in an inconclusive and paralyzing civil conflict is not the outcome that he's looking for," Obama said at a news conference in Paris.
Obama said he does not disagree with Putin -- with whom he met on Monday -- on the necessity of a political resolution to Syria's conflict. But he said there remains discord over the fate of Syrian President Bashar al-Assad, who the United States insists must leave power as part of a political transition. But he said the reality on the ground in Syria could change Putin's calculus.
