“The other thing with the terrorists is you have to take out their families, when you get these terrorists, you have to take out their families. They care about their lives, don’t kid yourself. When they say they don’t care about their lives, you have to take out their families,” Trump said.
That sounds an awful lot like a war crime to me.
How is it a war crime? Specifically.
Not if the whole family consists of terrorists
If you really believe that you should lead an effort to try both President Obama and President Bush, as well as whoever did the target planning for many of the missile and bomb attacks launched during their terms in office.
There are plenty of instances where bombs were dropped or missiles fired at targets where family members of the target were known to be present. In some cases the drone operators saw them before they pressed the fire button.
Plenty of innocent people die during wars, which is one of the many reasons to try to avoid them.
