Following American independence, the next occurrence of an attack on American soil was during the War ofalso with Britain, and also the first and only time since the end of the Revolutionary War in which a foreign power occupied the American capital the then capital city of Philadelphia was also occupied by the British during the Revolution.
After the Civil War, the threat of an invasion from a foreign power was small, and it was not until the 20th century that any real military strategy was developed to address the possibility of an attack on America.
European threats[ edit ] Until the early 20th century, the greatest potential threat to attack the United States was seen as the British Empire. To that end, military strategy was developed to not only forestall a British attack, but also attack and occupy Canada.
Similar plans  existed for a 20th-century war with Mexico, although the ability of the Mexican Army to attack and occupy American soil was considered negligible, as demonstrated by the Mexican reluctance to accept the provisions of the Zimmermann Telegram.
Mexican rebels led by Pancho Villa did briefly invade the U. According to the plan, Canada would invade the United States as quickly as possible if evidence of an American invasion was found. The Canadians would gain a foothold in the northern U. They would also destroy key bridges and railroads.
The plan had detractors, who saw it as unrealistic, but also supporters who believed it could conceivably have worked. On the opposite side of the Atlantic, Imperial German plans for the invasion of the United States were maintained from tobut were Could the nazi takeover of the seriously considered because the German Empire had insufficient resources to carry them out successfully.
Early versions planned to engage the United States Atlantic Fleet off Norfolk, Virginiafollowed by shore bombardment of eastern cities. Later versions envisioned a land invasion of New York City and Boston. The American Campaign Medal was awarded to military personnel who served in the United States in official military duties.
Military strategy instead focused on submarine warfarewith U-boats striking American shipping in an expanded Battle of the Atlanticparticularly an all-out assault on U.
Adolf Hitler dismissed the threat of America, stating that the country had no racial purity and thus no fighting strength, further quoted that "The American public is made up of Jews and Negroes ". Bywith U-Boat losses soaring and with the occupation of Greenland and Icelandit was clear to the German military leaders that the dwindling German armed forces had no further hope to attack the United States directly.
In the end, German military strategy was in fact geared toward surrendering to America, with many of the Eastern Front battles fought solely for the purpose of escaping the advance of the Red Army and surrendering instead to the Western Allies. The team was quickly captured and put on trial as spiesrather than prisoners-of-wardue to the nature of their assignment.
After the court found them guilty of espionage, six German agents were executed in the electric chair at the Washington D. Before his Machtergreifung in JanuaryHitler had already, inthought that the United States would be the next serious foe the future Third Reich would need to confront, after the Soviet Union.
Imperial Japan[ edit ] The feasibility of an attack on the continental United States by Imperial Japan was considered negligible, with Japan possessing neither the manpower nor logistical ability to successfully mount a full-scale invasion of the U.
During the war, Japan successfully occupiedbut later withdrew from, the Aleutian Islands of Alaska. Japan also conducted air attacks through the use of fire balloons. Six American civilians were killed in such attacks; Japan also launched two manned air attacks on Oregon the only time in the war that mainland America was bombed by enemy aircraft as well as two incidents of Japanese submarines shelling the American mainland.
In such an attack, nuclear warfare was projected to almost certainly happen, mainly in the form of intercontinental ballistic missile attacks as well as Soviet Navy launches of SLBMs at U. Bythe United States had developed a defense plan to repel a Soviet nuclear bomber force through the use of interceptors and anti-aircraft missiles, while at the same time launching its own bomber fleet into Soviet airspace from bases in Alaska and Europe.
By the end of the s, both Soviet and U. The concept thus developed of the nuclear triad where all three weapons platforms land based, submarine, and bomber would be coordinated in unison for a devastating first strike, followed by a counterstrike, accompanied by "mopping up" missions of nuclear bombers.
American nuclear warfare planning was nearly put to the test during the Cuban Missile Crisis. The subsequent blockade of Cuba also added a fourth element into American nuclear strategy, this being surface ships and the possibility of low yield nuclear attacks against deployed fleets.
Indeed, the United States had already tested the feasibility of nuclear attacks on ships under Operation Crossroads. Reportedly, during the Cuban missile crisis, one Soviet submarine nearly launched a nuclear torpedo at an American warship, yet the three officers required to initiate the launch the Captain, Executive Officer Vasili Arkhipovand the Political Officer could not agree to do so.
By the s, the concept of mutually assured destruction led to an American nuclear strategy which would remain relatively consistent until the end of the Cold War. Cyber and economic attacks[ edit ] Further information: Cyberwarfare in the United States The risk of cyber-attacks on civilian, government, and military computer targets was brought to light after China became suspected of using government-funded hackers to disrupt American banking systems, defense industries, telecommunication systems, power grids, utility controls, air traffic and train traffic control systems, as well as certain military systems such as C4ISRand ballistic missile launch systems.
