G-3, along with all the other intelligence organizations, made an improper evaluation of the situation before the war. Had we had our own intelligence organization, it's possible that our evaluation would have been different. It might even have been correct and we might have been a little better prepared. When we have only one viewpoint, we have harmony and tranquility, but we also have the danger of a single perspective. The biggest danger is that the viewpoint will be wrong.
Intelligence is evaluated by fitting together many fragments of conflicting information.
These fragments sometimes form a pattern. The trick is to know which fragments to use and which to discard. Most any preconceived pattern can be supported if only selected bits of information are used. Elimination of duplication is good at times, but when ideas or possibilities are eliminated under that guise, trouble is ahead. It is most desirable that different viewpoints, on intelligence matters especially, be laid out so that the top people can have the benefit of all the possibilities and act accordingly.
