Anyone that has actually spent any time in a country plagued with UXOs from CBUs or artillery or whatever (or indeed anti personell mines as well) can only be for a ban like this.
I've had the 'pleasure' of giving first aid to a kid that stepped on an UXO, it puts things into perspective. That was 5 years after the war was over and CNN left.
I don's see the yanks joining this initiative though.
