Iran is a rising power in the Middle East, and like it does with China, the U.S. government wants to do everything in its power to suppress Iran. From M. K. Bhadrakumar at indianpunchline.com:

Aircraft carrier USS Dwight D. Eisenhower transits through the Suez Canal towards the Persian Gulf , November 4, 2023
A massive US naval deployment in a wide arc of the so-called Greater Middle East is under way — stretching from Crete in the Eastern Mediterranean, into the Red Sea and the Bab el Mandeb and into the Gulf of Aden and all the way into the Gulf of Oman. This deterrent display may transform as large scale offensive operations and aims to rework the geopolitical alignments and bring them back to the traditional grooves of intra-regional rivalries in the Gulf region.
Ship spotters first said that as of Thursday, the aircraft carrier USS Dwight D. Eisenhower and its escorts were sailing just outside the Strait of Hormuz in the Gulf of Oman, and were approaching the Persian Gulf. A Pentagon official confirmed the location but would not say whether the carrier will enter the Persian Gulf passing through the Strait of Hormuz.
The US naval build-up in the region consists of another carrier strike group as well — USS Ford and its escorts — which last week moved away from Israeli coast and is now re-positioned to the south of Crete, according to ship spotters, apparently beyond the missile reach of Lebanon’s Hezbollah.
Apart from the two carrier strike groups, the US deployment also includes a three-ship Bataan Amphibious Ready Group with the 26th Marine Expeditionary Unit and several guided-missile destroyers — USS Bataan and USS Carter Hall operating in the northern portion of the Red Sea, and USS Mesa Verde in the Eastern Mediterranean along with the command ship USS Mount Whitney.
