Oh dear. Why do so many people have to analyse films so deeply. I always thought they were supposed to entertain, not invite intellectual analysis. The Sum of All Fears is excellent entertainment. What does it matter if bits are unbelievable? Surely, a fictional story is a vehicle for the imagination. As for anti-Semitism. P-lease.... Everyone I know who has seen this film has been delighted with it. It has great tension and often leaves you breathless. The actual nuclear incident breaks into the film with a shocking surprise, even though there is a considerable build up to it. It comes out of nowhere, just as it would in real life. Incidentally, the respective presidents are well portrayed. The 'halo' of advisers, good and bad, certainly exists in real life. I doubt that many decisions are actually unique to these individuals. Highly recommended entertainment to be enjoyed with a beer and a good selection of snacks.
