“No war but (the) class war” is a political saying that has been printed on many images. “No war ... but class war! : read ‘Libertarian struggle’” was on a sign in the United Kingdom that appears to date from 1974. It is not known who first used the saying, but it has been a popular slogan with many anti-authoritarian, anti-capitalist groups.
 
Political groups in both the United Kingdom and the United States have used the slogan. “No War but Class War” was on signs by the group Witness For Peace at a Duke University protest in 1988. “I bet you have a bumper sticker on you merc for ‘no war but class war?’” was posted on the newsgroup uk.politics.misc on May 15, 1998.
   
The slogan is frequently given by its initials. “NWBTCW” (No War But The Class War) was posted in the newsgroup talk.religion.buddhism on September 30, 2002. “No War But The Class War (NWBTCW) is a communist front organization that started in London and now has roots in the San Francisco Bay area. No War But Class War (NWBCW) is based in Boston” was posted on the newsgroup alt.politics.bush on August 3, 2008.
   
     
Wikipedia: No War but the Class War
No War But The Class War (NWBTCW) is a motto expressing opposition to capitalism used by anarchist and communist groups. It is also the name for a number of anti-authoritarian, anti-capitalist groups.
 
Group names
The first two NWBTCW groups appeared in London during the 1990–1991 Gulf War and the 1999 Kosovo War. Both groups, which included ex-members of the London-based Class War, dissolved after the respective war they were protesting stopped. The third NWBTCW group appeared in London following the start of the War in Afghanistan in October 2001.

The phrase was used in the first episode of the 1975 series Days of Hope, written by Jim Allen and directed by Ken Loach (both socialists), which caused controversy in Britain over its portrayal of the British military during World War I. A socialist who has deserted from the British army says, “I’m no pacifist. I’ll fight in a war, but I’ll fight in the only war that counts, and that’s the class war, and it’ll come when all this lot’s over.”

An amateur photographer, responding to my editorial letter about the Hinckley sign, has provided us with many photographs of the signs carried by WFP (Witness For Peace—ed.) members during the recent anti-Reagan demonstration at Duke. The signs speak for themselves. Listen to their message: “Condoms not Contras,” “Pee on Reagan. Not in a Cup,” “Long live the Revolution of the Sandinistas,” “No War but Class War,” “[Reagan] Wants to Make America Safe for the Rich,” “Say No to Reagan and Drugs for Arms,” “Just Say No to the Raygun (sic) Agenda.”

I don’t know who first came up with this slogan, but it has been an anarchist slogan for as long as I can remember (which is quite a long time) and probably for a very long time before that.

The day of the march, the front banner read, “No War But the Class War,” and through careful messaging, the group reframed their protest to oppose not only the policies of neoliberalism embodied in the IMF and WB but also nationalism, militarism, and war.

1. People get really weird when you tell them you oppose war in all forms.
2. “No War But Class War” needs to be said more, because there are a lot of people out there who like EVERY War But Class War.
