Gunboat diplomacy in the context of "Opening of Japan"

The Perry Expedition (Japanese: 黒船来航, kurofune raikō, "Arrival of the Black Ships") was a diplomatic and military expedition in two separate voyages (1852–1853 and 1854–1855) to the Tokugawa shogunate (徳川幕府) by warships of the United States Navy. The goals of this expedition included exploration, surveying, and the establishment of diplomatic relations and negotiation of trade agreements with the various nations in the region. Opening contact with the government of Japan was considered a top priority of the expedition, and was one of the key reasons for its inception.

The expedition was commanded by Commodore Matthew Calbraith Perry, under orders from President Millard Fillmore. Perry's primary goal was to force an end to Japan's 220-year-old policy of isolation and to open Japanese ports to American trade, through the use of gunboat diplomacy if necessary. The Perry Expedition led directly to the establishment of diplomatic relations between Japan and the western Great Powers, and eventually to the collapse of the ruling Tokugawa shogunate and the restoration of the Emperor. Following the expedition, Japan's burgeoning trade routes with the world led to the cultural trend of Japonisme, in which aspects of Japanese culture influenced art in Europe and America.

An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and hangar facilities for supporting, arming, deploying and recovering shipborne aircraft. Typically it is the capital ship of a fleet (known as a carrier battle group), as it allows a naval force to project seaborne air power far from homeland without depending on local airfields for staging aircraft operations. Since their inception in the early 20th century, aircraft carriers have evolved from wooden vessels used to deploy individual tethered reconnaissance balloons, to nuclear-powered supercarriers that carry dozens of fighters, strike aircraft, military helicopters, AEW&Cs and other types of aircraft such as UCAVs. While heavier fixed-wing aircraft such as airlifters, gunships and bombers have been launched from aircraft carriers, these aircraft do not often land on a carrier due to flight deck limitations.

The aircraft carrier, along with its onboard aircraft and defensive ancillary weapons, is the largest weapon system ever created. By their tactical prowess, mobility, autonomy and the variety of operational means, aircraft carriers are often the centerpiece of modern naval warfare, and have significant diplomatic influence in deterrence, command of the sea and air supremacy. Since the Second World War, the aircraft carrier has replaced the battleship in the role of flagship of a fleet, and largely transformed naval battles from gunfire to beyond-visual-range air strikes. In addition to tactical aptitudes, it has great strategic advantages in that, by sailing in international waters, it does not need to interfere with any territorial sovereignty and thus does not risk diplomatic complications or conflict escalation due to trespassing, and obviates the need for land use authorizations from third-party countries, reduces the times and transit logistics of aircraft and therefore significantly increases the time of availability on the combat zone.

American imperialism or US imperialism is the exercise of power or control by the US outside its borders. It operates through military conquest; military protection; gunboat diplomacy; unequal treaties; support for preferred factions; regime change; economic or diplomatic support; economic interference via private companies, or influence on local culture and media, potentially followed by intervention when American interests are threatened.

American imperialism and expansionism took the form of "New Imperialism" beginning in the late 19th century, although authors such as Daniel Immerwahr consider earlier American territorial expansion across North America at the expense of Native Americans to fit the definition. While the US has never officially identified itself and its territorial possessions as an empire, some commentators have done so, including Max Boot, Arthur M. Schlesinger Jr., and Niall Ferguson. Other commentators have accused the US of practicing neocolonialism—dominating territory via indirect means—which leverages economic power rather than military force.

American imperialism is the exercise of power or control by the US outside its borders. The US expanded its territory initially via conquest, later shifting to controlling/influencing other countries without conquest, using techniques such as alliances; aid; gunboat diplomacy; treaties; trade; support for preferred political factions; regime change; economic influence via private companies, exports of culture and media. Military interventions have been used to support allies, expel invaders, overthrow governments, and support US economic interests.
