Good grief. Will we ever learn? We tell our troops to get the job done, but first put shackles on their arms and legs. And then we blame them when anything goes wrong (or right)!
Remember, this whole emphasis or new rule that there should not be civilian casualties is something the global left put out to shackle the US military. While civilian deaths are regrettable, there is no rule that civilians can't or won't be killed in war zones. The US should not accept that and I don't think they have. Civilians have always died in war and will continue to do so.
The rule against civilian deaths applies to soldiers rounding them up and mowing them down. It does not apply to warfare.
Well if Pakistan officially allows al Qaeda thugs to fire from Pakistan, they better expect return fire.
How much brains does it take not to hang out next to armed killers firing stuff at US troops?
