Militarized interstate dispute
Type of state conflict

Militarized interstate disputes (MIDs) are conflicts between states that do not involve a full-scale war. These include any conflicts in which one or more states threaten, display, or use force against one or more other states. They can vary in intensity from threats of force to actual combat short of war. A MID is composed of a sequence of related militarized incidents, all but the first being an outgrowth of or response to a previous militarized incident. An initiator of a war need not necessarily be the same as the initiator of a preceding MID, since a MID can be started by a show of force, whereas the initiator of a war begins the actual combat. Under this definition, over 2,400 MIDs have been identified from 1816 to 2014 in the Correlates of War project.
For example, although the 2003 invasion of Iraq by the United States-led coalition would be considered a full-scale war, the bombings and disputes related to American, British, and (until 1996) French control of the Iraqi no-fly zone in the 1990s are described by Frank Wayman as a MID.
Research
Some of the findings from research on MIDs:
Research using a continuous measure of democracy shows that the most democratic nations have few MIDs with one another. There is an ongoing debate regarding whether it is the most authoritarian or the intermediate regimes that have the most MIDs.
When examining these MIDs in more detail, the disputes between democracies have on the average more hostility, but are less likely to involve third parties, hostility is less likely to be reciprocated, when reciprocated the response is usually proportional to the provocation, and the disputes are less likely to cause any loss of life.
Enduring militarized competition between democratic states is rare.

Why this record matters
The phrase “type of state conflict” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 11, 2026. The linked authority identifier is Q6851939. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1816, 2014, 2003 and 1996.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
