World peace? Did you ever looked at all the wars that happened since? Many involving the US army ... And not in a nice way... If you speak of the western world, the main reason for peace is the construction of the european union, creating much more cooperation between countries that had always been fighting each other. US foreign policy is not driven by peace, freedom or whatever propanganda created to have people's support but by self-interest. It's the same for any country.
