Those are the few countries that France needs to worry about.
Doesn't matter whether Estonia, Honduras, Laos, and Luxembourg can track their carrier, or not.
EDIT: In confined waters (like the Mediterranean), many more countries could track the carrier if they cared to. Even back in the 1950's, the Soviets got quite adept at loading "fishing boats" with electronic equipment, then trailing behind US Navy carrier groups.
