Military Expenditure by Country

This is a list of the military expenditure in millions of dollars by country. Not surprisingly, the United States is on top of the list with more than 663 billion dollars. Just wondering if only a fraction of this money was spent on human development instead of spending it on machines and purposes that only contribute in the escalation of human enmity. According to analysts, the United States is under so much debt that some even predict that humanity will witness the fall of America sooner or later, just like what happened in the former Soviet Union. Having lived in America for two years myself, i believe that America could very much invest the power of good in its people which i had lived and witnessed myself. Unfortunately, the current and former policies only worsened the situation and had sunk the US in deep economic and social troubles of its own. Anyways, here is the link to the list from Wikipedia:
