The US is sending a third aircraft carrier and thousands of additional troops toward the Middle East as President Donald Trump weighs renewed military action against Iran after the November midterm elections. The deployment includes the USS Theodore Roosevelt carrier strike group and the USS Makin Island amphibious group, carrying more than 2,000 Marines. Reports say the buildup could place three U.S. carriers and two amphibious groups around Iran by late November. Trump has indicated that further strikes remain possible after the midterms, while diplomacy with Tehran remains stalled. Does the growing U.S. military presence signal preparations for a wider Iran operation?
