How ought civilized people respond to members of a religious sect that preach hatred, revenge, and violent death and then practice what they preach, often to horrifying effect? If Clinton were being honest (a foreign concept, that), he would admit that it is hardly irrational for people to fear or feel antagonistic toward such barbarians, nor is it morally wrong to identify them as such.
You have to remember that not only does the former "Chicken in Chief" loathe the military, he obviously and evidently loathes the country the the military is tasked to protecting. Afterall, one cannot seperate their feelings for the military AND their mission, right?
