During the nuclear war Argentina wasn't hit by any powers and it remained in a stable mod, but the fear and the increase of refugees from the Northern Hemisphere led the government to temporarily suspend the constitution, but only few refugees arrived from the North, mainly Americans or Panamanians. The Argentinian government accepted these refugees, mainly from the US, Europe and Panama. These citizens were integrated into Argentina in some months. With the Falklands and South Georgia, reunited now under the Falkland State, the government tries to negotiate with the Falklands to unite them with Argentina, but in the end, all the tentative negotiations fail and so Argentina gives up the idea of taking the Falklands for the moment.
Annexation of the Falklands
Main Article: Falklands War
However, in 1966 the Argentine government was overthrown in a coup, replacing Isabel Martínez de Peron with Jorge Rafael Videla, leader of the militaristic junta. While this junta was less than friendly with the Falklands and cut many deals, it seemed unlikely that they'd take any action against the Falklands. However, in 1969, Leopoldo Galtieri became the new President of the junta. Four months into his leadership, his popularity proved to be extremely low, and a plan was hatched to improve public morale.
On the April 2nd 1970, Argentine troops landed in South Georgia, and overthrew the small group of Royal Marines still stationed there. With the conquering of all the Falklands in a few hours the marines stationed there were left free and given the possibility to return to England. By the end of the day Stanley had fallen and the government fell, and over the next few days the rest of the islands fell under Argentine control.
This event increased the popularity of Galtieri among the Argentinians and he used this even for gathering more popularity with the full annexation of the Falkland and South Georgia under Argentina. He also decided to end martial law and create a national day for the reunification of the Malvinas with their motherland.
At this same time, Argentines, often with little choice, were "encouraged" to settle on the islands, and Spanish was made the official language in many quarters.
In the late 70s the Royal Navy organized a trip to the southern hemisphere to see if any territory was hit or damaged. This convoy started from Cardiff and after having passed the Canadian and the American coast arrived at the Caribbean discover that all the ex-British colony ended them under the West Indies Federation. From there they arrived farther south near the South Georgia Islands. When the trip reached the island, they noted an Argentinian flag on the dock, so they communicated via radio why it was an Argentinian flag on a British possession and the Argentinian responded "Why, is not British?" However, as the convoy was given the possibility to take any British military equipment and any British citizens that wanted to come with them, almost the 10% of the Anglo population of the Falklands left the isles.
However, in 1980, after many economical crisis and the grown of power, Galtieri was deposed and accused of violation of human rights. Reynaldo Bignone, formerly a major in the army, was appointed President. There he started democratic reforms, though also granted amnesty to human rights abusers, himself including. In 1982 the first free elections for over two decades were held, with Raúl Alfonso elected as President, and promptly reversed Bignone's amnesties. Over the next few years he was to take out democratic reforms, preventing any further coups. On the 2nd April 1982, seven years after direct Argentine rule, the Falklands were granted to become a region of the Argentina, allowing democratic home rule. Whilst Spanish remained in official and educational use alongside English, many Argentines emigrated back to the mainland, though many stayed, too.
With the restore of the democracy Argentinia expose a boom in his economy and a grown in his wealth, with the improvement of the third sector new immigrants from Europe and America came in Argentina for work and live is accorded that at least 150,000 people arrive in Argentina in the last decades, this immigrations not only brings new people but also many opportunity for the Argentinians.
With the 2000s Argentina grew in the fastest numbers, becoming the second strongest nation in South America and also having the second largest economy in South America. Many see Argentina as the leading country in South America. In 2003, Argentina became a founding member of the League of Nations alongside many other nations and the United Kingdom. At this time relations between the two countries was rocky, but with the help of the League the two countries arrived at an agreement: Argentina will give the possibility to the Falklands to become independent or rejoin the UK whichever they wanted and in return, the United Kingdom will recognize sovereignty over Falklands.
