But a return of one win and a draw in a rookie season won't convince the masses of their worthiness to be included.
But it should, especially when historical context is applied. France entered what was the Four Nations (it became Five) in 1910 and won one game in 1911. They didn't win another Five Nations encounter until they beat Ireland in 1920 and it took until 1961 before they won their first title outright.
We think now of the French as a long-time giant of the game but really their history between 1910 and 1960 was, at best, moderate.
They won only 48 per cent of their games in that period and really, the coming of France was in the 1970s and 1980s.
Italy have found their integration into the Six Nations just as painful. Since their debut in 2000 - they won their opening game in Rome against Scotland - they have posted only nine wins and a draw from 65 encounters. They are yet to beat England or Ireland and six of their wins have come against Scotland. Only once have they won two games in a season.
The Six Nations is a grand old tournament, tough and challenging, but the Rugby Championship is surely more demanding. The travel burden is greater and it is relentless facing the teams ranked one, two and three in the world where in the Six Nations the rankings range from four to 11.
It has to also be remembered that Italy, for three years before their entry, were an unofficial part of the Five Nations, playing the nation with the bye.
Argentina, however, have no experience of tournament play outside of World Cups. Thrown in a shark-infested deep end, they need empathy and support to survive.
