The US can't just wipe out towns. We have signed the Fourth Geneva Convention in 1949. "The Fourth Geneva Convention relates to the protection of civilians during times of war "in the hands" of an enemy and under any occupation by a foreign power. "
Hmm, you've just explained why we've never truly "won" a war since WWII...
Tell me, do you think the jihadis are also signatories? The Geneva Conventions were for governing warfare between the 'civilized' nations that could develop their own technology, clearly their authors did not contemplate Turd World religious freaks who would be able to terrorize the populations of advanced nations whose citizens have modern notions of morality, including respect for individuals.
We're not fighting the Russians here, this is not the United Kingdom vs. Argentina in the Falklands, this is an enemy whose religious fanaticism excludes any moral benefit from acting with compassion to those who are 'infidels'. Their 'holy' book tells them to lie to us, to kill us, to enslave and torture us, unless we submit to their travesty of a religion.
They do not deserve the protections of a document intended to benefit people who can be entrusted to empower morally responsible individuals to governmental power.
