The USS Dwight D. Eisenhower in the Middle East
The Truman is a east coast ship. there are 2 carriers within strike distance of China. The Reagan and the Roosevelt. The LHA is a helo carrier, which travels half the speed and no fighter protection, so it doesn’t count. If they move the Truman to the Arabian sea, then I’d be concerned. I doubt they will move the Nimitz much farther than Hawaii leaving the west coast without a carrier....but with this transgender military leaders...who knows.
