This article examines the linkages by which time pressure influences national decision makers to initiate wars. It is argued that time pressure matters most significantly as an intervening variable at the decision-maker level in conjunction with system and subsystem level variables, such as changes in relative strike capability and alliance relationships, and state level variables like military strategy and doctrine. Most studies treat time pressure as having relevance during an acute crisis; in this article, time pressure is viewed as having an intermediate-term significance, that is, prior to the escalation phase or during the early phase of a crisis. It is shown that independent variables such as relative capability, alliance relationships and military doctrines are most likely to be associated with war initiation when they are mediated by time pressure. The article also distinguishes between immediate time pressure—that occurs during the escalation phase of a crisis—and intermediate time pressure, which can happen prior to, and at the onset phase of a crisis.
