The US military's strikes on Iran's nuclear sites were not a preamble to plans for regime change, US Defense Secretary Pete Hegseth said on Sunday, adding that private messages had been sent to Tehran encouraging them to negotiate.
Still, Hegseth warned Iran against following through with past threats of retaliation against the United States, and said US forces were postured to defend themselves, and take action if needed, Reuters reported.
"This mission was not and has not been about regime change," Hegseth told a reporters at the Pentagon. "The president authorized a precision operation to neutralize the threats to our national interests posed by the Iranian nuclear program."
The US strikes included 14 bunker-buster bombs, more than two dozen Tomahawk missiles and over 125 military aircraft, in an operation the top US general, General Dan Caine, said was named "Operation Midnight."
Caine said initial battle damage assessments indicated that all three sites sustained extremely severe damage and destruction, but he declined to speculate whether any Iranian nuclear capabilities might still be intact.
Caine said the US military had increased protection of troops in the region, including in Iraq and Syria.
"Our forces remain on high alert and are fully postured to respond to any Iranian retaliation or proxy attacks, which would be an incredibly poor choice," Caine said.
