They have much more than an aircraft carrier in the area. Try 3 aircraft carriers, 30 plus cruisers and destroyers, 25 subs, plus Japanese, South Korean and Australian naval assets. US also has moved B1, B2 and B52 into area. Probably about 80 of those along with 2 or 3 wings of F15. The buildup has been going on all month. There is no way they are going home empty handed.
