Americans why don't you join conmebol?. conmebol = south american's football ociation.?

I think you have a great team, however your team will not progress significantly if you continue in concacaf, concacaf is the weakest confederation in the world... So, why don't you join CONMEBOL? look, Australia doesn't play anymore in Oceania, they now play in Asia's football confederation.. Probably if you joined the CONMEBOL you wouldn't qualify to several world cups, however, your football level would progress significantly, conmebol is a very strong confederation, here we have great national teams, fantastic players, look, Messi is south american, we also have great tournaments such as copa libertadores or copa America, and my favorite south american tournament is indeed "south american qualifiers" south american qualifiers are very competitive, you really suffer a lot in south american qualifiers and in the end only very good teams qualify, but the teams that fail to qualify are still good... so what are your thoughts?
