I have forgotten the story where God is willing to spare the city if there is even one righteous soul there. I know we still have some in this country - many, but we are shrinking in number. I do think there is a connection to the fact that we are not having large families and teaching all these kids to love and serve God. The projected demographics are that the Muslims will soon outnumber us by huge, huge numbers - probably as scary a thought as any nuclear fears.
Sodom & Gomorah.
