** The [[TheNecrocracy Sorcerer Kingdom]] has secretly made plans for the eventual annexation of the [[TheKingdom Re-Estize Kingdom]].

Their pawn, however, turns out to be a man of [[TooDumbToLive unfathomable idiocy]] who one day decides to rob a convoy of humanitarian aid sent by the Sorcerer Kingdom to the Roble Holy Kingdom ([[SuspiciouslySpecificDenial whose recent misfortune they are completely unrelated to]]).

** A little over a century before the events of the series, the [[TheCaligula Elf King]] kidnapped and [[RapeIsASpecialKindOfEvil raped]] a [[SemiDivine god-kin]] of the [[TheTheocracy Slane Theocracy]], who was rescued by the [[EliteArmy Black Scripture]] before she could give birth. While the Slane Theocracy have always been [[FantasticRacism human supremacists]] and relationships with the Elf Country had always been tense as a result, [[ThisIsUnforgivable the incident was the final straw for the Theocracy]], who have been engaged with the elves in a war of extermination ever since.
** A much more dramatic example, without any political machinations involved, takes place at the end of Volume 16, when [[spoiler:Ainz finally learns that it was the Slane Theocracy who [[MoreThanMindControl brainwashed Shalltear]] in Volume 3. He immediately orders his followers to drop everything they are doing and to prepare his forces for war: ''they are going to'' '''''[[RoaringRampageOfRevenge annihilate]]''''' ''the Slane Theocracy''.]]

* In ''Manga/MariaNoDanzai'', the [[DeathOfAChild death of Kiritaka Nagare]] and the realization that [[NeverSuicide he did not commit suicide]] but rather was killed by a GangOfBullies turns his mother [[MamaBear Mari]] from a loving {{housewife}} to a [[KnightTemplarParent viciously vindictive crusader]] hellbent on [[BullyHunter ensuring the perpetrators die]] in [[CruelAndUnusualDeath the most painful, excruciating manner possible]].

* Nancy Pelosi visiting Taiwan on August 2, 2022, and Tsai Ing-Wen visiting the United States on March 30, 2023 is enough for the Chinese Communist Party to immediately declare war on Taiwan.

** Slappy Squirrel (who is a clear expy of the likes of Screwy Squirrel, Bugs Bunny and the may other characters who embodied this trope in the golden age of animation) will make your life hell if you cross her, even if it's just for petty issues. Just ask the neighbor she drove to insanity because said neighbor wouldn't let her throw away a soda can in her trash.

* ''WesternAnimation/DuckDodgers'': One two-parter was actually called "Of Course You Know, This Means War and Peace". It was mostly war, though, with the peace treaty being a trick for the villain General Z-9 to get access to codes to earth's defence's and invade the planet. The quote "This Means War!" was said by the Martian Queen early in part one.

* Non-humorous example on ''WesternAnimation/{{Gargoyles}}''. When Xanatos [[spoiler: turns Derek into a mutate]], Elisa tells him that it's war now, and that she won't give up until she gets him back for it.
