And Then There Were None

Think about what would happen to this world that we live in today, if a virus killed off all the males of the earth. Due to the continuing effects of the virus, women cannot have male children. Men, knowing they would all be dead within a couple of years, take steps to help the women survive after them. After all the men are gone, how will women set up their governments, industry, military, countries? Will a cure for the virus ever be found so that male children can once more be born to women?
