I suggested that it is foolish to be overly fastidious about killing civilians to get at these jihadists--not only in Iraq and Syria, but in other countries also. The very reason they are sheltering in cities is that they are sure the U.S. is so soft and decadent it lacks the will to cause heavy civilian casualties to get at them, no matter how horrific the atrocities they continue to commit. They are convinced Americans are so fastidious we simply can't bear causing civilian casualties, and they are using that weakness against us.
Under the laws of war, if civilians are killed in the course of attacking armed enemies who have taken cover among them, those enemies--and not the people attacking them--are unlawful combatants and responsible for killing those civilians. Fighting from amongst civilians, using them as human shields, is a war crime, just like fighting out of hospitals, schools, churches, or residences. The laws of war do not require the U.S. to let war criminals have a safe haven from which to plot the murders of more Americans, just because attacking them is likely to cause civilian deaths.
I could understand assisting Arab nations in fight ISIS, but I don't understand why we should make a huge commitment and send ground troops over...
The Arab Nations are to incompetent to deal with the problem. Which is why they have to rely on others to solve the problem.
I suppose Al Qaeda didn't have the ability to reach us here on U.S. soil, either, since they were operating out of Afghanistan, clear on the other side of the world. The U.S. only murdered millions of them because we didn't like them--not because of 9/11. When will this horrible, evil country stop hating on poor Muslims, just because they're brown and not Xtian???
