I tried to avoid this stupid USA or not discussion for months, but it's taking longer than I thought to get settled by itself. I'm against USA being here. Why? For the same reason India is not on the English language article language box. 

 India has 2-4% of English speakers   (that's 19 - 38 million people. According to wikipedia itself, the figure is between 50 million and 250 million (List of Indian languages by total speakers). Taking the 250 million figure (debatable), that's around 84% of the third most populated country in the world: United States. According to Languages in the United States, 82% of USA's population speak English as first language. So, theres a probability that there are more (second language) speakers of English in India than first language speakers of English in USA. Even the lowest figures (19 million) is more than double the population than Australia, and Australia is on the box, yet India is barely mentioned on the English language article. If India is not in the English language article's {{language}} box, I don't see why USA should be here.  

 Mexicans pursuing the american dream don't make USA a spanish speaking country, just a country with lots of spanish speaking immigrants.
