I don't think amm14 was suggesting that anyone is ahead of the US. I think amm14 is saying that the second-ranking country is Switzerland, not Australia.
Not sure what source amm14 is using but the wiki page https://en.wikipedia.org/wiki/List_of_Grand_Slam_champions_by_country shows Australia with 41 (singles) as of today. The single titles by country are currently USA 138, Australia 41, (West) Germany 32, Spain 31, Switzerland 28, Sweden 25. If you include all the doubles too and count each player separately (as there are pairs from different countries) the order is USA 487, Australia 182, Spain 65, Switzerland 54, Sweden 50, France 47
I got a little excited when I saw Australia and cheered ever so slightly, before I realised this quiz highlights that we're second in these categories... Wah!
I realise it's just my opinion but I find it terribly difficult to believe that India only has 200 million speakers of English. When I went there in 2001, everyone I spoke to in the street, including obviously very poor people, was able to speak English to some level except for one old lady. I suppose I was entirely in cities and towns. I just have my doubts over official figures - but I suppose that is all we have to go on.
And hang on - that source says that 38 million French people speak English!! Where are they all?
Suggest to change English (native) for English (first language). It could be argued that all countries with English as an official language have native English speakers. It's also the terminology used at the source (I guess) https://en.wikipedia.org/wiki/List_of_countries_by_English-speaking_population
If the extremist proponents of immigration really cared, you think you'd see China, India, Nigeria, Brazil, Pakistan, etc. listed as #2/3. Instead it's Germany and Saudi Arabia. Think about that. The countries with a billion people don't make the list.
I'm not sure if you misunderstood what the question was asking or if you're just spouting right-wing nonsense, but to me your comment does not make sense.
