Agree with second part, But what do you mean did not hit the mark? It hit the mark perfect atheism. Survival of the fittest etc. Why are you correct and him wrong?.
How did his ideas and policies further the prosperity and security of his people? He didn't even come close to eliminating the subhuman threats to his country....

And why "if atheism is true"? Why can't causality obtain without a higher power?
