The U. S. Defense Department has always been proud of its power on land, at sea, and in the air. And now, it’s increasing its attention to a fourth sector-space.
   Defense Secretary Donald Rumsfeld announced plans this week for changes that would include adding a four-star general responsible for space programs. Wolf Blitzer has more. The organization known for guns, ships and planes may be getting into a more cosmic business. More than any other country, the United States relies on space for its security and well-being. Defense Secretary Donald Rumsfeld is taking the Pentagon to another dimension, overhauling its space program, putting the Air Force at the helm, and appointing a four-star general to lead the way, elevating space, he says, to meet 21st century national security needs. Space issues are complex and merit a renewed focus. Senator Bob Smith, Republican, New Hampshire: There are nations out there who are hostile to us, and they are in space. They, they have such weapons as lasers, anti-satellite weapons, and electromagnetic pulse weapons, and we have to be ready to recognize that threat.
