US airstrikes on Iran set back the country’s nuclear program by one to two years, a Pentagon spokesman said, adding to uncertainty around the status of the country’s facilities after President Donald Trump said they’d been obliterated.

Chief Pentagon spokesman Sean Parnell said allies share the US sentiment about the degradation of Iran’s nuclear abilities “and the fact that we have degraded their program by one to two years — at least the intel assessments inside the department assess that.”
