”Courage, above all things, is the first quality of a warrior.” – Carl von Clausewitz
Armchair warrior (noun) – fighting, but only verbally, from the comfort of one’s living room.
Armchair warrior – a pejorative term which describes activities such as advocating use of armed forces instead of diplomatic means in resolving conflicts or speaking out in support of a battle, fight or a war. I couldn’t have found an exact etymology of this word but one of the first examples of its usage appeared in a series Twilight Zone. In one of the episodes, the author Rod Serling wrote a speech that is made by a time traveller. The speech was aimed at a banker who was calling for sending young soldiers to fight a war against American Indians in the late 1800s.
