Buenos Aires is the capital and largest city of Argentina. It is geographically located on the southern shore of the Río de la Plata, on the southeastern coast of the South American continent. Greater Buenos Aires is the third largest conurbation in Latin America, with a population of about 13 million. In English, Buenos Aires means "Fair Winds" or "Good Air." After the internal conflicts of the 19th century, Buenos Aires was federalised and removed from Buenos Aires Province in 1880. The city limits were enlarged to include the former towns of Belgrano and Flores, which are both now neighbourhoods of the city. During most of the 19th century, the political status of the city remained a sensitive subject. It was already capital of Buenos Aires Province, and between 1853 and 1860 it was the capital of the seceded State of Buenos Aires. The issue was debated more than once on the battlefield, until the matter was finally settled in 1880 when the city was federalised and became the seat of government, with its Mayor appointed by the President. The Casa Rosada became the seat of the office of the President. In addition to the wealth generated by the fertile pampas, railroad construction in the second half of the 19th century increased the economic power of Buenos Aires as raw materials flowed into its factories; Buenos Aires became a multicultural city that ranked itself with the major European capitals. The Colón Theater became one of the world's top opera venues. The city's main avenues were opened mostly between 1880 and 1940, an era that also saw the construction of South America's then-tallest buildings and first underground system.

Cyberwarfare

Cyberwarfare refers to politically motivated hacking to conduct sabotage and espionage. It is a form of information warfare sometimes seen as analogous to conventional warfare although this analogy is controversial for both its accuracy and its political motivation.

Cyberwarfare has been defined by government security expert as actions by a nation-state to penetrate another nation's computers or networks for the purposes of causing damage or disruption. The Economist describes cyberwarfare as the fifth domain of warfare, and William J. Lynn, U.S. Deputy Secretary of Defense, states that as a doctrinal matter, the Pentagon has formally recognized cyberspace as a new domain in warfare which has become just as critical to military operations as land, sea, air, and space.

In 2009, President Barack Obama declared America's digital infrastructure to be a strategic national asset, and in May 2010 the Pentagon set up its new U.S. Cyber Command (USCYBERCOM), headed by General Keith B. Alexander, director of the National Security Agency (NSA), to defend American military networks and attack other countries' systems. The United Kingdom has also set up a cyber-security and operations centre based in Government Communications Headquarters (GCHQ), the British equivalent of the NSA. In the U.S. however, Cyber Command is only set up to protect the military, whereas the government and corporate infrastructures are primarily the responsibility respectively of the Department of Homeland Security and private companies. Cyber warfare is the least common type of warfare and has not been used effectively to date.

In February 2010, top American lawmakers warned that the threat of a crippling attack on telecommunications and computer networks was sharply on the rise. According to The Lipman Report, numerous key sectors of the U.S. Economy along with that of other nations are currently at risk, including cyber threats to public and private facilities, banking and finance, transportation, manufacturing, medical, education and government, all of which are now dependent on computers for daily operations. In 2009, President Obama stated that cyber intruders have probed our electrical grids.

The Economist writes that China has plans of winning informationised wars by the mid-21st century. They note that other countries are likewise organizing for cyberwar, among them Russia, Israel and North Korea. Iran boasts of having the world's second-largest cyber-army. James Gosler, a government cybersecurity specialist, worries that the U.S. has a severe shortage of computer security specialists, estimating that there are only about 1,000 qualified people in the country today, but needs a force of 20,000 to 30,000 skilled experts. At the July 2010 Black Hat computer security conference, Michael Hayden, former deputy director of national intelligence, challenged thousands of attendees to help devise ways to reshape the Internet's security architecture, explaining, You guys made the cyberworld look like the north German plain.
