'an unexploded bomb cannot destroy the flour mill. if the flour mill is not destroyed by the bomb, goldstone`s claim of war crime is spurious and and deceitful' One bomb didn't explode. This does not mean that no bombs exploded. Secondly, even one unexploded bomb means that the IDF specifically targeted the building for destruction. Even if they had to finish the job with tanks or artillery the point is it proves intent to destroy the flour mill. That is why your post is spurious, though more likely just hapless.
