<<How did we avoid this problem during WWII?
<<Did we evacuate the children of Hiroshima or Dresden before we burned the city?>>
No, I think we considered the heinousness of the enemy, the general support they and their crimes received from the local population, the relative absence of any real Resistance movements in the population, the atrocities inflicted by them, the threats posed by their still-formidable military if the conflict were to continue and them just decided, Fuck 'em, they don't deserve to live anyway.
<<Al Queda chooses the location of the fight , they bear 100% of the responsibility , after all ,they have the choice of simply stopping , we don't have that choice.>>
You could say that of any enemy - - they can simply stop resisting. OTOH the U.S.A. can stop enabling the dispossession of the Palestinians and the ongoing theft of their land, etc.
al Qaeda lives in the shadows, it still doesn't justify your bombing of defenceless villages. If you don't have the balls to go in after them on the ground, don't sacrifice the lives of innocent children to your own cowardice.
