The term "cease fire" is typically used in military or conflict situations to indicate a temporary stoppage of hostilities. Antonyms for this phrase could include "continue fighting," "escalate conflict," "persist in aggression," or "prolong the war." These words all suggest a continuation of violence, rather than a peaceful resolution. It's important to remember that cease fires are often a critical step towards ending violence and establishing peace, as they allow parties to negotiate and hopefully come to a diplomatic solution. However, in some situations, a cease fire may not be desirable or feasible, which is where these antonyms might come into play.
