You're either with us, or against us
The phrase "you're either with us, or against us" and similar variations are used to depict situations as being polarized and to force witnesses, bystanders, or others unaligned with some form of pre-existing conflict to either become allies of the speaking party or lose favor. The implied consequence of not joining the team effort is to be deemed an enemy. Since 2001 it has most commonly been attributed to former US President George W. Bush, who famously used the phrase after 9/11 at the launch of his anti-terrorism campaign.
The statement generally is a descriptive statement identifying the beliefs of the speaker(s), and thus state a basic assumption, not a logical conclusion. It may also be interpreted as a speech act. It is sometimes interpreted as a splitting or a false dilemma, which is an informal fallacy.
Some see the statement as a way of persuading others to choose sides in a conflict which does not afford the luxury of neutrality. Only when there is absolutely no middle ground or additional alternatives does the phrase hold validity as a logical conclusion. The phrases are a form of argumentation.
Use of the phrase
- The Synoptic Gospels attribute the following quote to Jesus of Nazareth: "Whoever is not with me is against me, and whoever does not gather with me scatters" (Matthew 12:30), as well as its contrapositive, "Whoever is not against us is for us" (Luke 9:50; Mark 9:40).
- Vladimir Ilyich Lenin, in a speech discussing the Chief Committee for Political Education, told the assembled delegates that "It is with absolute frankness that we speak of this struggle of the proletariat; each man must choose between joining our side or the other side.

- George Orwell wrote in his 1942 essay "Pacifism and the War", "If you hamper the war effort of one side you automatically help that of the other. Nor is there any real way of remaining outside such a war as the present one. In practice, ‘he that is not with me is against me’. The idea that you can somehow remain aloof from and superior to the struggle, while living on food which British sailors have to risk their lives to bring you, is a bourgeois illusion bred of money and security."
- Benito Mussolini declared in speeches across fascist Italy: "O con noi o contro di noi"—You're either with us or against us.

You can't fight us, we are Americans."
- Hillary Clinton said on September 13, 2001: "Every nation has to either be with us, or against us. Those who harbor terrorists, or who finance them, are going to pay a price."
