MGS4 theme/story could become true???

Well maybe not to the extent tht PMCs could be contracted out (although a possibility) but could it become reality tht in the future war is a common occurance throughout the streets??? After all we could already be seein signs wht wit nuclear energy and the crisis of resources (especially oil) could definitely lead to war becoming common....hell is it so far-fetched to think tht maybe i might be forced to become a soldier by the government simply to fuel the future war economy....could war simply become another trick to show a countries superioty over the other on a more regular basis??? i dread to think..
