Those who sign here petition the United States government to secure funding and resources, and begin construction on a Death Star by 2016.
By focusing our defense resources into a space-superiority platform and weapon system such as a Death Star, the government can spur job creation in the fields of construction, engineering, space exploration, and more, and strengthen our national defense.
To refute your opposition points:
1) Your $850Quad price estimate was done by 'a few economics students'. Let's get a real estimate going.
2) Blowing up planets for the sake of mining would create jobs. Why is the administration against that? A Death Star can also be used for destroying Earth-bound asteroids or Xeno-Communists.
3) Use some American ingenuity to solve the exploit (maybe a grate?)
