Of course you don't. Which was the first World Cup that the US ever qualified for? Let's focus on answering that one for now.
1934
Although I am a football history ball jumbie, I still not update date on the qualification/invitation scenario. I know in the first WC and a couple after that, the teams used to be invited. In the first WC most Euro teams declined. It too far, the conditions to primitive, etc, etc. When the WC start to be a hit, more countries wanted to play and they started qualifications. Had the US ever quaklfied before 1990. Did they get an invite for the Brasil 1950 or did they qualify. How may times did get invitation and how many times did they qualify?
