In a 2010 interview,  Khalezov explained that you can't build a skyscraper in NYC without an approved demolition plan.  On 9/11, the WTC's demolition plan was put into action to demolish the complex.

Khalezov learned of this demolition plan from his job in the Soviet Union.  He had worked in the nuclear intelligence unit and under an agreement between the Soviet Union and the USA, each country was obliged to inform the other of peaceful uses of nuclear explosions.   The WTC was constructed with 3 thermo-nuclear devices deep in its foundations.

Note: underground nuclear explosions do not produce mushroom clouds.  This is only ever seen when the explosion takes place above ground.  On 9/11, the explosions were deep underground.

I know the very notion that the WTC was brought down by nukes is utterly preposterous but go check the definition of 'Ground Zero' in the old dictionaries you have at home.  You'll find that there would only be one definition and that would be something like:
'the point directly above, below, or at which a nuclear explosion occurs'.

After 9/11, the US government sent people round to every bookshop and public library on the planet to replace ALL the dictionaries with amended versions which have an expanded meaning of 'Ground Zero'. The new versions (even of old editions) have 2 extra meanings which are:
2: the center or origin of rapid, intense, or violent activity or change
3: the very beginning : SQUARE ONE
