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.
