The precision weapon, within generalized boundaries, will perform roughly equally well in all circumstances, provided a target can be identified. Time scales may change and levels of effort may change, but the end result—a victory for the force making the best use of precision—is unlikely to change unless other factors (such as loss of national will, changing international support, "wild cards," etc.) enter play. The single most important factor is how well the decision-maker, both military and political, appreciates what precision weapons can and cannot accomplish, what mechanism or process has been established to assess the appropriateness of their use, and the rules of engagement that govern their use.
