U.S. Ambassador to the United Nations Nikki Haley said the U.S. isn’t trying to force President Bashar al-Assad out of office, but that it’s hard to imagine him remaining in office for much longer.

“It’s a matter of time before he’s gone,’’ she said on CBS.

Haley also said the situation in Syria is moving in the right direction, but reiterated warnings to Syrian President Bashar Assad against the use of chemical weapons or military force in the region of Idlib, the last major area held by the armed opposition. She said the U.S. has no intention of forcing Assad from power but said she believes his days are numbered.
