He says the pause does not reflect any concerns about the military’s ability to defend U.S. interests.

“We’re always assessing, you know, our munitions and where we’re sending them,” he told reporters. “We can’t give weapons to everybody all around the world.”

Pentagon says U.S. strikes ‘completely obliterated’ Iran’s nuclear sites

Parnell said the strikes ordered by President Donald Trump in June set back Tehran’s nuclear program by more than a year.

“We’re thinking probably closer to two years,” he told reporters at his second briefing since Trump’s latest term began.

“We destroyed the components they would need to build a bomb,” Parnell said. “We believe Iran’s nuclear capability has been severely degraded.”
