    We only need to slow it's arrival by 7 minutes or so and we'll be out of the way when it gets here.

    But my problem is, it seems under current technology, we don't have years lead times.  It doesn't do any good to predict a 50% chance of hitting.  If we slow that object down by 7 minutes, we might turn a miss into a hit.  So for schemes like this, if we have to wait until it's close to be certain of it's trajectory, we'll need lots of force.  Sort of a Titanic/iceberg situation.

    Even Democrats can be asses. Look at Rahm Emanuel.

    •  Worse case scenario: turning "that miss into a (0+ / 0-)

      hit." Horrors.
