We voters are the problem; the leaders are doing what they have been lead by us to believe is most important. The linked system provides sufficient power to avoid collisions with Ceres and above type objects---assuming the larger the object the more time we'll have to alter its course because it can be discovered earlier. Late discoveries of smaller objects can also be diverted in much shorter intervals. The system requires at least 200 years to design, build and implement--let's get started VOTERS ARISE

If you were an Earth hostile invader, where would you deposit a Ceres sized object to cause the most damage--off the southern tip of Africa or off the southern tip of South America on the Pacific side? The North Pole?
