I don't think america as a failed nation. If it is a failed nation, why most people talk about various incidents talking place in america.
Why they all compare their countries growth along with america in terms of economy, education as well technology.
I strongly agree with your thoughts because America has been still survive with the problems they are facing so I think America is a tough country. We can't deny that a lot of people want to become citizen of America so I don't think that America is a failed nation.
