Retired Lieutenant General Keith Kellogg on Friday maintained the U.S’s retaliatory strikes on Iran will not be sufficient, adding that President Joe Biden’s delayed action gives the Islamic State time to regroup and respond at a later time.

The U.S. Central Command (CENTCOM) confirmed on Friday that the United States has conducted airstrikes against more than 85 targets in Iraq and Syria belonging to Iran’s Islamic Revolutionary Guards Corps (IRGC) Quds Force and affiliated militia groups.

The strikes were retaliation against Iran following a drone strike that killed three U.S. service members on Sunday, Jan. 28. Several Republicans have blasted President Joe Biden for waiting too long to retaliate for the deadly attack.

Kellogg —in an interview with Fox News’ Larry Kudlow— maintained that the strikes were not only late but were insufficient. The retired general, Who served as an advisor to former Vice President Mike Pence during the Donald Trump administration, insists that the strike will not stop Iran from striking back at the U.S.

“It’s not going to be sufficient and I think I would caution everybody, this isn’t a time when you rip your shirt off and beat your chest that this is really cool because it shouldn’t be numbers, it should be what happens is the consequences from your attack,” Kellogg told Kudlow. “And look, what we’ve given the Iranians is a sanctuary. I’ve been through a sanctuary war before back in the years of Vietnam when Cambodia was a sanctuary, North Vietnam was a sanctuary. You allow a sanctuary, he’ll retreat, move back in there and respond later on.”

Kellogg blasted President Biden for the delay in the strikes before revealing that the aircraft that carried out the strikes could have done so two days earlier.

“Those packages were there, it just took presidential authority, and that’s who does it, to say go,” Kellogg said. “And he waited way too long. In fact, those aircraft, from what I understand, the B-1 bombers that took off came out of the United States, they lifted off this morning. They could have lifted off two days ago, three days ago.”
