I'm putting together a list of those that have publicly claimed there are nukes in the US. I'm hitting a brick wall. I've found lots of reputable sources that claim "someone higher up"..."government officials"..."the CIA"..."the FBI"...etc. But as you stated, very few actual names and titles to back up the statement. I will continue my search.
The NEIN report goes beyond merely claiming there are hostile nukes in the USA. The NEIN teaser suggests that we were close to losing a city, and according to some people here on the TM who subscribe to NEIN, the actaul report (as opposed to the teaser), suggests that we, in fact, captured one of the nukes near the United Nations in NYC. Again, I don't subscribe to NEIN, and so I don't know any more than what's alleged in the teaser and reported here by those who claim to have actually read the report.
