The verbs diffuse and defuse sound similar but have different meanings. Diffuse means, broadly, ‘disperse’, while the non-literal meaning of defuse is ‘reduce the danger or tension in’. Thus sentences such as
Cooper successfully diffused the situation
are regarded as incorrect, while
Cooper successfully defused the situation
would be correct. However, such uses of diffuse are widespread, and can make sense: the image in, for example,
only peaceful dialogue between the two countries could diffuse tension
is not of making a bomb safe but of reducing something dangerous to particles and dispersing them harmlessly.
