According to Russian reports, the main culprits for the 9/11 attacks operated within the governments of the US, the UK and Israel. According to a retired FXX agent specializing in Israeli counter intel revealed that nuclear devices were used on 9/11. These nuclear devices 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. All plutonium based warheads have a chemical fingerprint that can identify the type of design and where the PU was made and how old it is. This was the 911 blackmail on Bush 1 and 2, the illegal transfer of surplus US nuclear weapons to the Israelis and why the continued cover up, along with the stolen gold and stock fraud that was going on Wall Street etc. Only a 2 kiloton device was needed to drop the buildings. A 2 kiloton device will produce a fireball of apx 150 to 200 feet in diameter at over 4000 degrees
