Due to the replacement of large warheads on inaccurate missiles with smaller warheads on more accurate missiles, "you may logically conclude that unless your home is closer than 10 miles from the nearest probable target, you need not evacuate to avoid blast and fire dangers."
This statement suggests that, given the improved accuracy of newer missiles and their smaller warheads, people living further away from potential targets are less likely to need to evacuate during an attack.
