The issue of motherhood is no longer salient. In fact, the very first female bomber for Hamas posed in her last will and testament video with her two kids.

I did a study of soldiers returning from Iraq, and their levels of PTSD were much higher if they had had to shoot a woman or child, even if they knew the person was a suicide bomber.

When the bombers are women - and children, which I predict we'll see more of - the terrorists get more bang for their buck, because there's more media attention.

Acts perpetrated by women, particularly attractive women, get far more media attention.

It's cheap, and you have a thinking, breathing bomb that can adjust to circumstances and cross the street to hit another target if the original one doesn't look good.

A lot of movements use women's involvement to shame men when recruitment is sagging.

With a civilian target, female bombers tend to be more successful and cause more damage.
