Power projection (or force projection) is a term used in military and political science to refer to the capacity of a state to apply all or some of its elements of national power - political, economic, informational, or military - to rapidly and effectively deploy and sustain forces in and from multiple dispersed locations to respond to crises, to contribute to deterrence, and to enhance regional stability. This ability is a crucial element of a state's power in international relations. Any state able to direct its military forces outside the limited bounds of 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. While traditional measures of power projection typically focus on hard power assets (tanks, soldiers, aircraft, naval vessels, etc.), the developing theory of soft power notes that power projection does not necessarily have to involve the active use of military forces in combat. Assets for power projection can often serve dual uses, as the deployment of various countries' militaries during the humanitarian response to the 2004 Indian Ocean earthquake illustrates. The ability of a state to project its forces into an area may serve as an effective diplomatic lever, influencing the decision-making process and acting as a potential deterrent on other states' behavior. ==History== The ability to project power and exert influence on a global scale was only made possible with the Industrial Revolution and the associated modernizations in technology, communications, finance and bureaucracy; this finally allowed the state to create unprecedented amounts of wealth and to effectively marshal these resources to exert power over long distances. The first such industrial-technological power was the British Empire in the 19th century. As a maritime power, its strength and ability to project power to further its interests lay in the Royal Navy. A worldwide system of naval bases and coaling stations, a large logistical bureaucracy to oversee shipbuilding, the supply of coal, food, water, and sailors, and an industrial base for the manufacture and technological enhancement of the fleet were among the essential ingredients for this capability. During the First Opium War (1839–42), it was this capacity that enabled a British expeditionary force of 15 barracks ship The Anglo-French expeditionary force sent to shore up the Ottoman Empire against Russian aggression during the Crimean War (1853–56) was one of the first examples of a planned expeditionary power-projection campaign. It was the first campaign to use modern technology, including steam-powered warships and telegraph communications. Another illustrative example of industrial power projection, was the punitive British Expedition to Abyssinia in 1868 as a retaliation against Emperor Tewodros II of Ethiopia's imprisonment of several missionaries and British government representatives. The expeditionary force sent was a tremendous logistical and technological challenge at the time. Commanded by Lieutenant-General Sir Robert Napier of the Bombay Army, military intelligence was used to estimate the required size of the army and the difficulties of traversing the inhospitable terrain. A force of over 30,000 was shipped from British India to Zula on the Red Sea on a fleet of more than 280 steam ships, while an advance detachment of engineers built a large port with two piers, warehouses and a lighthouse, and constructed a 20-mile-long railway towards the interior. A road was also built for the artillery to be moved along with the help of elephants. After three months of trekking, the British force repelled an Ethiopian attack and bombarded the fortress of Magdala into submission; Tewodros committed suicide.〔Rubenson, ''Survival'', p. 268〕 In the Russo-Japanese War of 1904–05, the Japanese destruction of the Imperial Russian Navy's Pacific Fleet demonstrated Imperial Russia's inability to project force in the East. This immediately diminished Russia's diplomatic sway in that region. At the same time, Russia's western armies became less credible, as mobilization exposed organizational flaws and threw the western armies into chaos. This led analysts in Europe, such as German chief of staff Count Alfred von Schlieffen, to conclude that Russia would prove inept at projecting force in Europe, thus demoting Russia in European diplomatic relations. Many other actions can be considered projections of force. The 19th century is full of incidents such as the 1864 Bombardment of Kagoshima and the Boxer Rebellion. More recently, the Falklands War provided an example of the United Kingdom's ability to project force far from home. Other recent examples of power projection include the U.S.-led Invasion of Iraq and the NATO bombing of Yugoslavia. The ability of the U.S. Navy, the British Royal Navy, and the French Navy to deploy large numbers of ships for long periods of time away from home are unique projection abilities. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Power projection」の詳細全文を読む スポンサード リンク
