EVERYONE IN THE WORLD knows that the price of a sunken US Aircraft Carrier is the complete and total annhiliation of your nation via WMD. An aircraft carrier is a capital, strategic asset. It carries dozens of nukes...and up to 6000 personnel.
Fully loaded...to include the cost of replacement manpower it's worth upwards of $15bil.
You honestly think there is anyone in the chain of command that would nuclear? I don’t.
