A policy of deliberate ambiguity (also known as a policy of strategic ambiguity, strategic uncertainty) is the practice by a country of being intentionally ambiguous on certain aspects of its foreign policy or whether it possesses certain weapons of mass destruction. It may be useful if the country has contrary foreign and domestic policy goals or if it wants to take advantage of risk aversion to abet a deterrence strategy. Such a policy can be very risky as it may cause misinterpretation of a nation's intentions, leading to actions that contradict that nation's wishes.
