with religious extremists that kill and blow themselves up in the name of Allah, God or whomever?

How can you negotiate with people that walk into a marketplace and then proceed to blow themselves up taking lots of innocent civilians with them?

How can you negotiate with people that strap bombs to children, themselves and others?

How can you negotiate with people celebrate and cheer when innocent people are killed?

Please someone explain to me just how you negotiate with this.

IMO you can't, the same way you can negotiate with people that protest soldiers funerals, blow abortion clinics up, destroy property in the name of the environment.

Some people cannot be reasoned with.
