Francis Boyle, an international law authority at the University of Illinois, Champaign, says pursuant to national strategy directives adopted by Bush in 2002, the Pentagon "is now gearing up to fight and 'win' biological warfare without prior public knowledge and review." Boyle said the Pentagon's Chemical and Biological Defense Program was revised in 2003 to endorse "first-use" strike in war. Boyle said the program includes Red Teaming, which he described as "plotting, planning, and scheming how to use biowarfare."
