The term international crisis is widespread term without a single common definition. To some, it involves "a sequence of interactions between the governments of two or more sovereign states in severe conflict, short of actual war, but involving the perception of a dangerously high probability of war".
Lebow gives a breakdown of three types of international crises:
- Justification of Hostilities. One of the nations decides, before the crisis starts, to go to war and constructs a crisis to justify it. The pattern of justification is almost always the same: Rouse public opinion, make impossible demands, try to legitimize the demands, deny your real intentions then employ the rejection of the demands as a reason for war. A recent example, commonly employed by critics of George W. Bush, is the Iraq disarmament crisis, which precipitated the Iraq War.
- Spinoff Crisis. The nations are involved in a war or crisis with another nation or nations and this precipitates another crisis, e.g. the Lusitania incident in 1915.
- Brinkmanship. Intentionally forcing a crisis to get the other side to back down. The Cuban Missile Crisis of 1962 is a well-known example of brinkmanship.
With the exception of a justification of hostilities, the study of international crises assumes that neither side actually wants to go to war, but must be visibly prepared to do so. In the words of Groucho Marx, "Always be sincere, even if you don't mean it".
- limited escalation
- test of capabilities
- "drawing a line"
- Buying time strategy
- Conveying commitment and resolve to avoid miscalculation by the adversary
List of defused crises
International crises tend to result in war, almost by definition; they are then remembered best not as crises but as causes of wars.
