As I Christian I will say this person is horribly misguided and/or Biblically illiterate.  A Nation (at least the way she is using the term) cannot "repent" at least in a Biblical sense, which is what she seems to be implying, by displaying the ten commandments, school prayer or anything else. People are the only ones who are commanded to repent, and doing these "good things" she references are meaningless to God without the inner conversion God requires (being Born Again of the Spirit of God) in order for man (and woman) to be justified before God, if enough people are converted and begin to interact with society, the society may "change".  Moral Standards are what the Catholics try to use, look at how that worked out.
