The U.S. is assembling its biggest naval force near Iran since 2003. By late October, the carriers Theodore Roosevelt, George H.W. Bush and George Washington are expected to operate in the region at once, with more than 20,000 sailors and Marines and hundreds of aircraft, according to the New York Times.

Pentagon planners have also prepared options for a roughly three-day campaign against the IRGC’s rebuilt missile launchers, stockpiles and drone infrastructure.
Interceptor worries

Officials are worried about shrinking interceptor stocks after Iran attacked at least 13 ships in the Gulf since September. Trump, however, said the U.S. would not attack Iran before the Nov. 3 midterms.
