Once the problem of warning is linked with its implications for action, it becomes significantly redefined. Early warning of a possible crisis is desirable not in and of itself but insofar as it provides decision makers with an opportunity to make a timely response of an appropriate kind that might be otherwise impossible. Warning gives the decision maker time to decide what to do and then to prepare to do it. Warning provides an opportunity to avert the expected crisis, to modify it, or to redirect it into some less dangerous and less costly direction. On occasion, warning may provide an opportunity to deal with a conflict-of-interest situation or misperceptions before they lead to a military conflict.
A number of experienced intelligence and policy specialists have endorsed the need for developing a response "repertoire" that includes a wide array of responses, some small, possibly covert, and low cost, others large, public, and more costly. The rationale that "the response must fit the warning" is a simple one, but not one easily realized. The response repertoire, of course, should include the many different responses that can be made by nongovernmental organizations.
