Iran may try to retaliate against the U.S. after a stealth strike hit three key Iranian nuclear facilities, though the regime lacks the capabilities to make a “significant escalation,” an expert on the Middle East and U.S. national security told Fox News Digital on Sunday.

Jacob Olidort, the director of the Center for American Security at the America First Policy Institute, said Iran is “a lot of bark right now,” and anticipated that there “might be a small bite” from the regime directed at the U.S.

“I do foresee some kind of face-saving efforts,” Olidort said, noting that Iran could potentially launch cyber-attacks or attacks on infrastructure in the region.

Iran has already launched more missiles at Israel in the wake of the U.S. military’s Operation Midnight Hammer, striking at least 10 impact sites and injuring at least 20 people in Israel.

The U.S. strikes may now have hindered Iran’s nuclear program by upwards of a decade, according to Olidort, though he said that the timeframe largely depends on what actions or agreements the U.S. and Iran make in the days to come.

The U.S. launched a surprise strike using B-2 stealth bombers on Iran’s Fordow, Natanz and Isfahan nuclear facilities on Saturday. 

Gen. Dan Caine, chairman of the Joint Chiefs of Staff, said during a briefing at the Pentagon on Sunday morning that the full extent of the battle damage to the facilities would take time to assess.

It remained unclear as of Sunday whether any enriched nuclear material was destroyed in the U.S. strikes or if Iran had moved the material beforehand.
