How should I translate "cold war" in Latin? I can see two ways to approach this, using a classical phrase for a similar hostile political situation, or finding a suitable adjective for "cold" to go together with bellum. There are several adjectives for coldness of some kind, and the most appropriate one I found is frigidus (see L&S, II.C) as it means both cold and frightening. However, the best choice might have nothing to do with temperature. How would you go about expressing cold war in Latin?
