While it's true that chemical warfare played a significant role in the conflict, the term "chemists' war" isn't widely used in historical literature.

Here's why:

* Other factors were more prominent: The war was characterized by unprecedented technological advancements, trench warfare, and the rise of nationalism. These aspects were considered more significant than the use of chemical weapons.

* Chemical weapons were not a primary weapon: While devastating and horrifying, chemical weapons were largely used defensively, to disrupt enemy advances or to clear trenches. They were not the decisive factor in the outcome of the war.

* The term is not commonly used: Historians and academics typically refer to the war using other terms like "The Great War," "The First World War," or "The War to End All Wars."

While chemical weapons were a horrifying aspect of World War 1, it is incorrect to label the war as "the chemists' war."
