Alas, that has two problems: (1) US military spending is our own national version of socialism, in which we prop up communities by providing massive state subsidies, along with housing, healthcare, education and more to a large group of people (2) because of (1), it is hard to convince elected representatives to cut these expenditures because of the very real and direct impact they will have on their communities.
Although both D & R representatives experience the above somewhat equally, there is some imbalance in the relationship between D & R representatives and the military-industrial complex, and that leads to us to a situation where cutting these expenditures is even more difficult than it would be if the only factors were 1+2 above.
