ICBMs have a habit of not being recallable. Once it is in the air, the only abort possible is destruction of the missile. Unfortunately, that still leaves a lot of shrapnel on a ballistic trajectory to the target.
They get to the target in 30-60 minutes. If you are so confused that you're going to change your mind in 30 minutes, don't launch.

There is no one on this planet who can't live without the Internet for the duration of a flight. If you are so insanely important, buy the plane's service.

People who also break into computer systems and deface web sites? A handful.
