Buttigieg responded the U.S. already has the means to protect its assets in the Middle East and said he thinks “our national security policy has to be to avoid escalation in the Persian Gulf.”

Tensions with Iran have been high since the Trump administration pulled out of the Obama-era nuclear deal and reinstated sanctions on Tehran.

More recently, officials ordered the accelerated deployment of the USS Abraham Lincoln carrier strike group to the region along with a B-52 bomber task force.

Iranian officials responded last Monday announced they have increased their capacity to produce enriched uranium.
