Why is defense spending 54% of our federal discretionary spending? Why do we spend more than the next 7-8 countries in defense spending COMBINED (China, Saudi Arabia, Russia, UK, India, France, Japan, Germany)! We need to spend on biomedical sciences. Non-defense R&D. Remember President Eisenhower on the military-industrial complex. Increased defense spending leads to more phony wars and paradoxically threatens out national security.
