For years, various disinformation agents have been attempting to sabotage the 9/11 truth movement with claims that "mini-nukes" or "nuclear devices" were used to demolish the World Trade Center. The fact that the Twin Towers and WTC7 (Building 7) were destroyed in a series of controlled demolitions is not in doubt; more than 1,400 architectural and engineering professionals have called for a new, truly independent investigation and cited evidence of controlled demolitions at all three collapsed WTC steel-framed high-rises.
This goes along with the no-planes theory - both obvious spin to divert focus from the question of who's to blame. So there are nukes with explosions small enough to only damage part of a skyscraper?
