The Pentagon has in recent days moved the Dwight D. Eisenhower Carrier Strike Group from the Persian Gulf into the Gulf of Aden, off the coast of Yemen, to support a potential U.S. response to attacks, said one of the officials, both of whom were granted anonymity to speak about sensitive plans. The military has also provided options to commanders to strike the Houthis, the official said.The Biden administration has been reluctant to respond militarily against the Houthi attacks on commercial shipping in recent weeks for fear of provoking Iran, which backs Hamas and Hezbollah in Yemen as well as the Houthis. Previously, the Pentagon had recommended the administration not do so.
