Permanent Zero Infrastructure or PZI is where a nation is reduced to ZI, and then not permitted to rebuild its infrastructure at any point again in the future. It is, by some, considered to be a death knell for a given nation. Nations sentenced to PZI are expected then to either leave Cyber Nations altogether or delete their nations and create new ones anonymously. What can be problematic is that anyone who gives the designated nation traceable aid may also be subject to attack for an indefinite period. So sometimes the PZI victim's friends will be demolished as a means to punish him.
