Defeatism
Defeatism is the acceptance of defeat without struggle, often with negative connotations. It can be linked to pessimism in psychology, and may sometimes be used synonymously with fatalism or determinism.
In politics, defeatism is used for one's perceived cooperation with the opposition party. In wartime and on the front lines of war, defeatism is synonymous with treason. The term covers soldiers who refuse to fight or voice doubt about the national policy of their own faction.
