If any member of the family should die whilst in the shelter, put them outside, but be sure to tag them first for identification purposes
The US seems to be developing nuclear weapons for a limited strategic role. This is a bad thing. While I'm all for nuclear weapons; they have kept the peace since WW2 and led to the development of technologies which guarantee humanity a limited future; their correct role is in a Mutually Assured Destruction role. The idea that limited use of nuclear weapons is acceptable is extremely dangerous, and likely to lead to a ruinous nuclear war.
