As America approaches the next century, we face both an uncertain world and a promising future. Our challenge, as a service and as a Nation, is to sustain that promise and secure the future. In the years to come, America's military will continue to play a pivotal role. That role will be a stabilizing one, founded on the shared principles and traditions of all the services. Increased cooperation is the cornerstone for success. The primary responsibility of America's military is to deter potential adversaries or fight and win wars decisively. To improve the way we do business, we must reconsider this core responsibility in terms of how America's military forces actually project power. At the foundation of this approach is power projection. Power projection is a means to influence actors or affect situations or events in America's national interest. It has two components: warfighting and presence. Warfighting is the direct application of military force to compel an adversary. Presence is the posturing of military capability, including nonbelligerent applications, and/or the leveraging of information to deter or compel an actor or affect a situation. A sound national military strategy depends on coherent warfighting and presence strategies.
