Regarding the Ralph Bush letter on dereliction of duty concerning the Benghazi affair, let us make a comparison:
Benghazi had four deaths.
In contrast, the Iraq War between 2001 and Feb. 5, 2013, left 4,475 dead and 32,220 wounded U.S. service members. There were 991 amputations 797 of which were of major limbs. The Afghanistan War saw 2,165 killed and 18,230 wounded. There were 724 amputations; 696 of those involving major limbs.
The estimates of monetary cost including long-term veteran care of Afghanistan, Iraq and Pakistan eventually total as much as $4 trillion, according to a 2011 Congressional Research Service Report and Brown University Research.
