Whether one believes this Arab tie-in account or not... the other obvious reason McVeigh would have blown up up the OKC Fed Building was in direct retaliation for the outrageous actions of the U.S. Government in Waco - not born from a generalized hatred of the government by right wingers. After all it was done on the Waco anniversary... And McVeigh - if he is to be believed said as much... A no brainer to me...
Ok, but how did he make such beautiful clean and perfect cuts on those interior I beams?
