USS Nimitz in the context of "Force projection"

In politics, hard power is the use of military and economic means to influence the behavior or interests of other political bodies. This form of political power is often aggressive (coercion), and is most immediately effective when imposed by one political body upon another of less military and/or economic power. Hard power contrasts with soft power, which comes from diplomacy, culture and history.

According to Joseph Nye, hard power involves "the ability to use the carrots and sticks of economic and military might to make others follow your will". Here, "carrots" stand for inducements such as the reduction of trade barriers, the offer of an alliance or the promise of military protection. On the other hand, "sticks" represent threats - including the use of coercive diplomacy, the threat of military intervention, or the implementation of economic sanctions. Ernest Wilson describes hard power as the capacity to coerce "another to act in ways in which that entity would not have acted otherwise".

Power projection (or force projection or strength projection) in international relations is the capacity of a state to deploy and sustain forces outside its territory. The ability of a state to project its power into an area may serve as an effective diplomatic lever, influencing the decision-making processes and acting as a potential deterrent on other states' behavior.

This ability is a crucial element of a state's power in international relations. Any state able to direct its military forces outside its territory might be said to have some level of power projection capability, but the term itself is used most frequently in reference to militaries with a worldwide reach (or at least significantly broader than a state's immediate area). Even states with sizable hard power assets (such as a large standing army) may only be able to exert limited regional influence so long as they lack the means of effectively projecting their power on a global scale. Generally, only a select few states are able to overcome the logistical difficulties inherent in the deployment and direction of a modern, mechanized military force. Allies and partners can take up or share some of the burden of power projection. One measure of the capability of a state to project power is the loss-of-strength gradient, until a culminating point is apparent to others, once an operation is underway.

Chester William Nimitz (/ˈnɪmɪts/; 24 February 1885 – 20 February 1966) was a fleet admiral in the United States Navy. He played a major role in the naval history of World War II as Commander in Chief, US Pacific Fleet, and Commander in Chief, Pacific Ocean Areas, commanding Allied air, land, and sea forces during World War II.

Nimitz was the leading U.S. Navy authority on submarines. Qualified in submarines during his early years, Nimitz later oversaw the conversion of these vessels' propulsion from gasoline to diesel, and then later was key in acquiring approval to build the world's first nuclear-powered submarine, USS Nautilus, whose propulsion system later completely superseded diesel-powered submarines in the United States. Beginning in 1917, Nimitz was the Navy's leading developer of underway replenishment techniques, the tool which during the Pacific war would allow the American fleet to operate away from port almost indefinitely. The chief of the Navy's Bureau of Navigation from 1939 to 1942, Nimitz served as the Chief of Naval Operations from 1945 until 1947. He was the United States' last surviving officer who served in the rank of fleet admiral. The USS Nimitz supercarrier, the lead ship of her class, is named after Nimitz.
