The officials said this is not in response to any new threats from Iran. President Trump has said he wants U.S. troops out of the Middle East, and it's not clear if the White House will approve sending any or all of the requested troops.
Acting Defense Secretary Patrick Shanahan told reporters on Wednesday the U.S. does not want to provoke Iran, and "our biggest focus at this point is to prevent Iranian miscalculation." Earlier this month, the U.S. hastened the deployment of an aircraft carrier strike group and B-52 bombers to the region. U.S. officials have remained tight-lipped about any potential Iranian threats, merely saying there are maritime threats. Catherine Garcia
