Assuming that you are referring to the USA, our policy is to have by far the largest and most advanced military on the planet, with the ability to extend force to remote corners of the globe within hours. Also, our policy is to have a massive nuclear armament which can be used at any time to destroy any country or even the population of the entire planet. I don't think we need to be directing any more of our media studies graduates into the engineering just to help out our armed forces.
So when we have to buy all the electronics in them from China and have the software designed in India and we can't get them to any of the remote corners of the Earth because our schools have been teaching that the Earth is flat and was created in 4004BC
