Preemptive war at the expense of future taxpayers and thousands of lives is an entirely different animal. Through the gift of hindsight, we should all agree that the situation was handled poorly. The present value of the total cost of these engagements would likely have been enough to cover the cost of health care for those who either cannot afford it, or are in extreme situations.
It is hypocritical to support spending on wars while arguing against increasing healthcare expenditures given the nature of the healthcare market. Modern day guns vs. butter that has left our country worse off!
