Unfair

An afghan's life is much much lesser than american's or an Israeli's?
This is UNFAIR.

In one of the most serious accusations of war crimes to emerge from the Afghan conflict, Gibbs recruited other soldiers to murder civilians he called "savages" after he took over command of a US army squad in Afghanistan's Kandahar province in November 2009.
This psychopathic "solider" who can be compared to Nazi's and early-American settlers and South African racists gets only 25 years with the possibility of 10 years in prison?

When will they learn? Until he does the same of his own people? Ridiculous.
