For the U.S. and its allies the Gulf War became the euphoria war. ''Eu'' is the Greek word for ''good/well,'' and euphoria is the response to news which is ''well-borne,'' easy to take.
Eugene and eugenics pertain to being well-born in another sense. Euclid means good fame, and Eunice good victory (nike). Eucharist is good charism or favor; a eulogy is a good word; euphemism is good speech which softens a hard word (e.g., ''passing'' for ''death''); euphony a good sound; euthanasia a good death.
The eucalyptus tree has a well-covered flower -- as opposed to an apocalypse (an uncovering or a revelation). The Euphrates is good for crossing. Eupepsia is good digestion (whence ''Pepsi'' cola). A messenger (angel) of good tidings is an eu/angelist, more easily said as evangelist.
