Why are submarines and torpedoes blunt instead of being pointy?

Most aircraft have pointy nose to be reduce drag and some aren't because they need to see the ground easily. But since a submarine or torpedo doesn't need to see then why aren't they pointy? Also ww2 era subs had sharo fronts.

Many answers, but one thing most people don't realize about fluid dynamics:  Notice the subs are more tapered on the back that the front.

It is MUCH easier to 'push aside' air/water than it is to 'return' the air/water.  

Pushing it aside is very easy.

Getting the air/water to 'flow' properly behind you without causing vortexes or cavitation is much more difficult, and where the majority of your drag will originate from.
