A retired officer specialising in Israeli counter intelligence has claimed that nuclear devices were used on 9/11 – and were a modified version of the W-54 artillery shells that were provided to the Israeli's between 1988 and 1998 from US stockpiles.
According to the Russian insider – chemical analysis done on the fallout at ground zero has identified the chemical/radiation footprint of the warheads used in the attacks as being of US/Israeli origin.
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. According to file ENW57.pdf on page 66.
