Here's an overhead shot of the ruins of the WTC North Tower and all the nearby buildings taken on the afternoon of September 11. 2001. Look at how that ruination blasted all those buildings. Would you believe it? All that damage was done by puffs of air blown out from the collapsing stories of the North Tower! Nothing but puffs of air! Would you believe it? No? Would you believe it was military grade incendiaries and explosives pre-planted in the tower that blew these hundred ton sections of beams 200 feet away and washed a burning cloud over the area like a volcanic pyroclastic cloud? Get smart, please! It's been 20 years! Can't you just take a look and use your common sense?
Information can be extracted from this photograph. Notice how the square faces of the tower broadcast the damage forcefully but the corners of the tower were not able to do that so much. That's how you can know that the force was ejected from the tower from internal explosives placed floor by floor. If this had been a nuclear bomb, even a small one, the blast damaged area would have been circular. And any nuclear blast would have been far too uncontrollable. There would have been radiation poisoning all over New York which would have rendered the city uninhabitable.
Besides that, the political fallout (an atomic era phrase, you notice) from a nuke exploded in New York City would have been even more unpredictable. It could have led to a nuclear confrontation. The perpetrators of the 9/11 crimes wanted to provoke a Conventional war, more specifically a low level insurgency war, not a nuclear war. The people who think the WTC towers were brought down with the aid of nuclear bombs are not thinking straight. Some of them may be deliberately stopping you from thinking straight. And how about those who promote even wilder nonsense like it's all a laser show or space age exotic energy beams did it? This is misdirection and it's deliberate.
Use your common sense. Put yourself in the mind of the perpetrators: what did they want and what political result did they get? That tells you who they were. These were military demolitions experts from special forces (Israeli special forces. I've got the evidence archived) doing a job for the neocons who needed a New Pearl Harbor to reorient America towards the implementation of the Wolfowitz Doctrine.
They wanted to destroy 7 countries in 5 years and "remake the Middle East." It turns out that they ended up setting a fire that threatens to burn down the USA.
Sol gel nanothermite is an explosive of unprecedented power which was developed by Laurence Livermore National Laboratories during the 1990s. I have downloaded the paper by the scientists who developed it. They brag about the abilities of this explosive. A small fragment of it, perhaps a quarter of a gram or less, produced a rapidly expanding ball of pyroclastic gas which looks by the photo they include to be at least two meters in diameter. This material, they brag, can be mixed with paint or fire retardant foam and sprayed on. It is inert and safe until ignited by radio controlled fuses – no detonation chord needed. There was a crawl space under every one of the 110 floors of the WTC towers. Sprayed with nanothermite laced fire retardant foam that four foot crawl space could be the way to turn all the trusses and the steel floor pans and the four inches of concrete on them and all the furniture on those floors and under the ceilings below those floors into dust.
