belligerati
Literary people, authors — literati — who promote wars of aggression.
I am not, in this instance, referring to the belligerati - Salman Rushdie, Martin Amis and chums - ever-present in the liberal press on both sides of the Atlantic.
Where it comes from
Blend of belligerent + literati which is also the plural of belligerātus.
