We have a very solid confirmation on this. Back during the 1980s, Israel showed her inventory of Davy Crockett tactical nuclear warheads to one of our editors, who at the time was a senior NATO intelligence official. These early “micro-nukes” were taken out of the US inventory in 1978 and “disappeared.”
According to a retired FXX agent specializing in Israeli counter intel: The type of nuclear devices used on 911 were a modified version of the W-54 nuclear artillery shells that were covertly provided to the Israelis between 1988 and 1998 from US surplus stockpiles illegally exported during the Bush/Clinton era.
Chemical analysis done by DOE Sandia was able to identify the chemical/radiation footprint or fingerprint of the warheads based on samples taken after 911 of the fallout at ground zero. (Editor’s note: Nuclear weapon use at ground zero is confirmed from multiple sources)
Melted steel and iron oxide or “nano thermite” is a byproduct of the very high gamma-ray / neutron flux induced into the central steel core. The radiation dissolves the steel into iron oxide, consuming the carbon and silicone in the steel. This explains the missing steel columns and the very important clue of the “vaporized’ 20-ton antenna tower atop the South tower. The upward blast of radiation literally vaporized it. Video evidence proves this to be true. (Editor’s note: Tower issue a vital one.)
The Saudis also have a stash of W-54s acquired from the US under Bush2. (Editor’s note: Confirmed) The Israelis have also provided them to India, Brazil, China, Taiwan, Japan, North and South Korea, etc. (Editor’s note: All but South Korea confirmed. Canada had been believed to be the source of Brazilian nuclear weapons.)
Due to overuse as a fast breeder reactor by the Israelis, Dimona suffered a “steam explosion”, IE a flashover indecent due to neutron criticality back in the late 1980s under Bush 1. This shut down its operation for many years until repairs could be made. It now only operates at very low power levels due to neutron absorption damage to the containment vessel. Now mainly used for isotope production. This forced the Israelis to turn to stolen nuclear stockpiles from the US for the continuation of their nuclear program.Censored VT Restored: Too Classified to Publish — Russia Opens Files on Nuclear 9/11 and Israeli Proliferation – Veterans Today | Military Foreign Affairs Policy Journal for Clandestine Services
