This Means War



""Of course you realize, this means war!""

- Groucho Marx, then Bugs Bunny

Now you've gone and done it.

A declaration that someone has broken the last straw, crossed the Moral Event Horizon, hit the Berserk Button or otherwise gone too far. The person making this declaration will now commit themselves to unleashing every ounce of asskicking they have at you until they get their way, and will not allow anything to stop them.

If the offended party is a Karmic Trickster, expect much Slapstick to follow. The Japanese have a specific cultural sub-trope and Stock Phrase for this: This Is Unforgivable!. May lead to a character exhibiting Crouching Moron, Hidden Badass, Let's Get Dangerous and similar qualities. Compare It's Personal. See also Pretext for War, when the trigger is a blown out of proportion to start the war.

You can expect that this declaration will be followed by a Roaring Rampage of Revenge and/or a No-Holds-Barred Beatdown.

Not to be confused with the 2012 romantic action-comedy film.

Anime and Manga

 * Also a Crowning Moment of Awesome, Luffy and the crew (Mostly Sogeking) from One Piece declare war on the World Government by not only shooting the Government Flag, but burning it as well. As it stands atop a major governmental base. Being watched by hundreds of marines.
 * Later, Admiral Kizaru is fighting with four of the most powerful rookie pirates in the world. He's clearly toying with them, but doesn't go for the finishing blow. Then one of them hits him with a surprise attack that cuts him in half and blows the pieces to smithereens. After he pulls himself back together, he's clearly had enough. He then declares the fight is over and dispatches them all in a matter of seconds.
 * Luffy has now declared war on
 * In Berserk, Guts gives a Rousing Speech variant of this against
 * Theresia declares war on Guts simply with a look. It's true that an actual declaration happens on the following page, but the look conveys the message a lot better. And is also rather scary.
 * Volume 3 of Hellsing has Millenium essentially declare war on Hellsing when they openly send one of their operatives, backed up by troops from the local law enforcement, to attack Alucard and Seras, live on national television no less. Just in case they didn't get the message, Volume 4 has them send a messanger to Hellsing headquarters with a live link to the Major, so that he can pretty much say "Let's fight!".
 * The homunculi of Fullmetal Alchemist caused major problems for themselves because of this trope. Before, Mustang knew pretty much nothing about the homunculi and consequently was not involved in trying to stop their evil schemes. The moment one of them  , he quietly went into a sort of chronic Heroic BSOD mode and became such a danger to them that Lust finally decided.
 * In the Grand Prix Arc of Yu-Gi-Oh!, Ziegfried is portrayed as a pompous fop who barely acknowledges Rex and Weevil as legitimate threats in the first round of the tournament (and they clearly are not; he defeats them and their Ace monsters in one turn) and treats Joey the same way in the second round... Until, that is, Joey manages to summon Jinzo and actually hurt him. Then he starts paying more attention and playing seriously.

Comic Books

 * Played for drama in the Astro City story "Serpent's Teeth", when an alternate-timeline version of Jack-in-the-Box's son uses Jack's "Of course you realize, this means war" as motivation to become a Knight Templar on the city's criminals... without realizing Jack was quoting Bugs Bunny.

Live-Action TV
"The Doctor: The street. They left her in the street. They took her face, and just chucked her out and left her in the street. And as a result, that makes things... simple. Very very simple. Do you know why? Inspector Bishop: No. The Doctor: Because now, Detective Inspector Bishop, there is no power on this earth that can stop me!"

 * Defied in the later episode, "Doomsday":

Admiral Nagala has taken personal command of the Fleet aboard the battlestar Atlantia following the complete destruction of Picon Fleet Headquarters in the first wave of the attacks. "How? Why?" doesn't really matter now. What does matter is that as of this moment, we are at war. You've trained for this. You're ready for this.

 * In Gossip Girls fourth season Chuck declares war on Blair after she drives Eva away, though one might wonder where he feels entitled to declare war over something like that after he sold Blair for a hotel and slept with her nemesis in the previous season.

Rome was so angry that it threw out all its kings, founded The Roman Republic, defeated the Etruscans in battle. And oh yes, took over the world. You wouldn't like Rome when she is angry.

Tabletop Games

 * Traveller: Do not do anything that louses up the Imperium's internal economic and political cohesion. Small wars between sub-states are ok; after all boys will be boys. But if you extend your war to far and bother your neighbors, use WMDs, or otherwise become to much trouble then you will receive a visit from the Space Marine s.

Video Games
"Specs: Of course you realise. This means war! Peepers: WAR! Whizzer: WAR!"
 * Subverted in The Godfather game. Shopkeepers and racket bosses will fight back if you apply too much pressure on them and you won't be able to get a payout from them... but since your pressure-application would probably have involved hitting them, shooting them, harming or killing innocents, all this does is mark them as Too Dumb to Live.

 * Said verbatim by the Eddy the Wizard in Yet Another Fantasy Gamer Comic. But then again, he has good reasons too.
 * Chaos of Life and Death almost does this, but doesn't due to a coin toss. But still, you have to wonder. How indirect can he get?
 * The Whiteboard: "You realize, of course... that this means War."

Western Animation
"Emory: Hey, maybe we should just back off. I mean, this is how fight starts. Oglethorpe: This is not a fight... THIS IS A WAR!"
 * Looney Tunes: A Bugs Bunny Catch Phrase of course ("Of course you realise, dis means war!") -- any time Elmer Fudd, Yosemite Sam or other buffoon harasses him to this point.
 * Similarly, his Tiny Toons counterpart Buster Bunny would say "It't time to party - Buster-style!" in the same kind of situation.
 * The Animaniacs episode "King Yakko" has the bad guy say "this means war" when his first attempt to take over Anvilania fails.
 * In some old Disney toons, Donald Duck would utter "This is the last straw!" before going medieval on whoever dared to push his Berserk Button way too much.

Real Life
""I fear that all we have done is awakened a sleeping giant, and filled it with a desire for vengeance.""
 * The immediate lead-up to World War I is famously complicated, but suffice it to say that this phrase got tossed around a whole lot right after Archduke Ferdinand was assassinated, as centuries-old political and ethnic tensions started to unwind.
 * On October 28, 1940, the Italian Ambassador to Greece presented a three-hour ultimatum to Prime Minister Ioannis Metaxas, demanding that Italian troops be allowed free passage to unspecified strategic points throughout Greek territory. Today, Greeks acclaim Metaxas' reply via "Ohi Day," or "No! Day," but Metaxas' actual response was "Alors, c'est la guerre!"
 * The picture above is the USS Arizona burning in Pearl Harbor. Japanese Naval Marshal General Isoroku Yamamoto is alleged to have said:


 * Although he probably didn't say those exact words, he did think that way... and he was right.
 * President Roosevelt said something more true to the trope title: "Yesterday, December 7, 1941--a date which will live in infamy..." If this doesn't sound badass to you, remember what "infamy" means: what he essentially said was "This Is Unforgivable!, and we shall never forget it." Less than one hour after those words were spoken, America officially declared war. Notably, except for a reciprocal declaration against Germany and Italy a couple days later, this was the last formal Declaration of War by the United States.
 * Charles Francis Adams was the American ambassador to England during the American Civil War. He was convinced that a British company was building warships for the Confederacy.

 * While not a formal declaration of war, after the British government began executing the captured rebel leaders of the 1916 Rising in Ireland well-known Home Rule supporter John Dillon rushed to London and warned Asquith (Prime Minister of the time) to halt the executions, saying: "You are washing our whole life work in a sea of blood." This was promptly ignored, leading to public opinion in Ireland swinging to support of the rebels, and, well, the rest is history.
 * Before the Six Day War, Israel specifically said that blocking the Straits of Tiran meant this. They weren't kidding.
 * Likewise several maritime powers have a standing This Means War on anyone who captures Istanbul. The reason for this is that Constantinople keeps the Russian fleet bottled up in the Black sea.
 * The Latin phrase for this is Casus Belli and this is the version often used in diplo-speak. Actually it sounds scarier in English then in Latin despite the reputation of the original Latin speakers.
 * After the attack on Saguntum in the beginning of the Second Punic War the Roman ambassador to Carthage went before the Carthaginian Senate and said that he carried in the folds of his toga peace or war and demanded that they choose. The Carthaginians said "you choose". So the Roman said he let fall war. And the Carthaginians said, "We accept it".
