As soon as it was revealed that a reporter for Progressive magazine had discovered how to make a hydrogen bomb, a group of firearm (火器) fans formed the National Hydrogen Bomb Association, and they are now lobbying against any legislation to stop Americans from owning one.
　　"The Constitution,” said the association’s spokesman, “gives everyone the right to own arms. It doesn’t spell out what kind of arms. But since anyone can now make a hydrogen bomb, the public should be able to buy it to protect themselves.”
　　"Don’t you think it’s dangerous to have one in the house, particularly where there are children around?”
　　"The National Hydrogen Bomb Association hopes to educate people in the safe handling of this type of weapon. We are instructing owners to keep the bomb in a locked cabinet
　　and the fuse (导火索) separately in a drawer.”
　　"Some people consider the hydrogen bomb a very fatal weapon which could kill somebody.”
　　The spokesman said, “Hydrogen bombs don’t kill people—people kill people. The bomb is for self-protection and it also has a deterrent effect. If somebody knows you have a nuclear weapon in your house, they’re going to think twice about breaking in.”
　　"But those who want to ban the bomb for American citizens claim that if you have one locked in the cabinet, with the fuse in a drawer, you would never be able to assemble it in time to stop an intruder (侵入者).”
　　"Another argument against allowing people to own a bomb is that at the moment it is very expensive to build one. So what your association is backing is a program which would allow the middle and upper classes to acquire a bomb while poor people will be left defenseless with just handguns.”
