2 light swats per 1M pop lost.  2 light swats can be exchanged for 1
heavy swat.

Secret Cards (in addition to 1 swat per 1M pop lost):

    For 2M and 5M losses, roll D6 for number of clothespins.

    For lose turn, 10M and 25M anal insert with irritant or 10 swats
    with heavy paddle if insert in use.

Spinner sections:
  Large areas (45 degrees each):

    Radioactive beta rays kill another 5M.

    Additional 1M are engulfed in the fireball.

    No appreciable radiation fallout.  Remove D6 clothespins.

    bomb shelter saves 2M.  If no pop lost remove insert & clothespins.
    If any pop lost, only remove insert or clothespins, not both.

    Lethal doses of gamma rays kill another 10M.  Apply Irritant to
    nipples.

    Radioactive fallout kills another 2M.

  Small areas (22.5 degrees each):

    Dirty bomb!  Double the yield.  Use heavy paddle instead of light.

    Explodes a nuclear stockpile, triple the yield.

    DUD warhead, no effect.  Everyone can remove inserts & clothespins.

    Missile booster explodes on launch (or B70 runs out of fuel).
    Peppermint/wintergreen/mouthwash on crotch.
