noun
Refers to an ideology or policy that emphasizes military power and the use of force, often in political contexts.
その国の武断主義は国際社会から批判された。
That country's militarism was criticized by the international community.
軍国主義 is a more common term for militarism, often associated with pre-WWII Japan. 武断主義 is less frequent and may carry a nuance of rule by military force rather than a broader ideology.
Compound of 武断 (military decision/force) and 主義 (principle/ism). The exact historical derivation is uncertain; it is a Sino-Japanese term likely coined in the modern era to translate Western concepts of militarism.
