Bill Gertz of the Washington Times looks at the proposed Defense Budget and notes that in there is a request for money to develop a "rock penetrating Nuclear weapon here.

The Pentagon is seeking $419.3 billion for fiscal 2006, a 4.8 percent increase, and wants to renew work on a rock-penetrating nuclear bomb that could be used against underground bunkers in places such as Iran and North Korea.
    Defense Secretary Donald H. Rumsfeld recently asked the Energy Department to spend $18 million over the next two years to finish a study on the Robust Nuclear Earth Penetrator, or RNEP, which congressional opponents of nuclear weapons sought to kill this year by cutting all funding.

Godd idea to have what you may need in inventory....
