Forgive me, but I find it hard to believe that our 2 billion budget for Israel, combined with modern range detectors cannot produce a result that doesn't require us to boil/roast civilians alive. But that just might be the optimistic side of me.
I am not saying you are not right, just that if we really wanted to put our heads together to find a solution, I think we could have come up with something that doesn't border the literal definition of a war crime.
