What does unilateralist mean?
A unilateralist is someone who favours unilateralism—acting, deciding, or imposing a policy alone rather than through agreement with other parties. In political and diplomatic writing, the word usually describes a person or faction that wants a government to undertake an action without first securing the consent of other states or institutions. It is especially associated with debates over nuclear disarmament, arms control, and foreign policy, although it can apply more broadly whenever one side proceeds without consultation. The term may sound critical because unilateral action can deny others a voice, but it is also used neutrally to identify a doctrinal preference. In general prose, “supporter of unilateralism” is often clearer than the compressed noun “unilateralist.” The word is formal and relatively uncommon, yet it usefully labels both an individual advocate and, by extension, a wider political stance. Its force lies in the contrast it draws between independent action and coordinated, multilateral decision-making.
nounA unilateralist is a person who advocates unilateralism: taking action, making a decision, or imposing a policy without the agreement or participation of other parties. The term is most often used in discussions of international relations, diplomacy, arms control, and disarmament.
- A person who favours unilateral action, especially by a state acting without the agreement or participation of other parties.
"The treaty prompted fierce opposition from unilateralists who favoured reducing the nuclear arsenal without outside verification."
"Senior unilateralists argued that the treaty should be abandoned without another vote."
"The survey found that many unilateralists supported reducing the nuclear arsenal without a multilateral verification regime."
The regular plural is used when referring to multiple advocates of unilateralism.
"Several unilateralists called for the programme to continue without international approval."
The name is politically literal: Latin uni means “one,” while latus means “side.”
