The 2007 Rugby World Cup was remarkable for both the country of Argentina and the sport of rugby. The national rugby team, commonly known as, Los Pumas made history in defeating historically powerful teams including France, Ireland and Scotland on way to finishing third. This result was no small achievement. It was massive as it meant that Argentina finished the World Cup ahead of highly fancied teams including Australia, New Zealand and hosts France. All have previously hosted the World Cup. In fact, Argentina are the only team to reach the Rugby World Cup semi finals who have not yet hosted a Rugby World Cup.
Following the success of 2007 the sport in Argentina has grown to give the country, at present, over 91,000 registered players. The sport itself, is on track to become a fully professional sport in Argentina. Los Pumas are now able to play in any city in Argentina and fill the stadiums. Since the World Cup this is precisely what has happened as the profile of the national team has resulted in rugby growing to previously impossible heights. It is this success combined with the history of rugby in the country which perfectly demonstrates the merits of Argentina hosting a Rugby World Cup.
Los Pumas are to enter the Southern Hemisphere's premier rugby tournament, the Tri Nations in 2012. They will therefore play Australia, New Zealand and South Africa home and away annually. The opportunity to host these elite rugby country's in venues across the country will further underline the merits of Argentina hosting a World Cup. 2023 looms as the ideal time for Argentina to host a Rugby World Cup because, aside from being the first time that it would have been hosted in the Americas, it would mark more than a decade of Argentina's involvement in the Tri Nations. With England hosting in 2015 and Japan in 2019, it would logically be time for a Southern hemispere country to host in 2023. Given that at this time Oceania would have hosted three World Cup's, Africa one, Asia one and Europe four, the Americas as a region will merit hosting the 2023 Rugby World Cup due to this fact alone.
With a population of 41 million and a friendly timezone which would enable games to take place at times which are good for powerhouse rugby countries from Africa, Europe and Oceania, the question is not why should Argentina host a Rugby World Cup. Rather the question is, why shouldn't they?
