The USS Theodore Roosevelt carrier strike group has departed for the Middle East, joining two other US aircraft carriers in the region, marking the largest military buildup since the 2003 Iraq invasion. This deployment is part of a strategic response to ongoing tensions with Iran, with an estimated 9,000 to 10,000 additional troops expected by the end of November. The situation remains fluid, with potential overlaps in carrier group operations as the US maintains a significant military presence in the area.
