Titles of this category should cover the events of a war as significant element of the storyline (even if the actual conflict doesn't get that much airtime). The opponents should be nations
at least (alien races, star systems, parallel universes etc. are fine as well); conflicts between smaller organisations would rather be categorized as "fighting".
An example for a real-world war would be
Hotaru no Haka, a fantasy war would be
Lodoss Tou Senki (OAV), a SF war would be
Saishu Heiki Kanojo.
Older anime titles, from the 80's back. What the actual amount of time that has to expire must be is unknown to me, but as a rule of thumb, a title should at least be 10-years old. Lupin III is an example of a classic title.
