Meaning and Definition
A political theory that suggests a small, initial event (like one domino falling) will trigger a chain of similar events.
Specifically, a Cold War-era foreign policy theory positing that if one country in a region came under communist control, neighboring countries would inevitably follow, like a row of falling dominoes. The term is also used metaphorically in other contexts (e.g., business, social sciences) to describe any predicted chain reaction of similar events.

The term originated in and is primarily associated with American political discourse. British usage is identical in meaning but less frequent, typically appearing in historical or political commentary about US policy.
Connotations
In both varieties, it carries strong historical connotations of the Cold War and the Vietnam War era. In modern critical discourse, it can imply a flawed or simplistic geopolitical analysis.
Frequency
Much more common in American English, given its origin in US political rhetoric. In British English, it is a recognized historical term but not part of active political vocabulary.
