Modernization of our nuclear capability isn't necessary a bad thing (if you assume MAD doctrine is effective and that the nuclear triad is a key piece of this).
Democrats roll back military spending and funnel that money to their domestic pet projects like environmental causes, fighting poverty, and improving education. Then, once a Republican is back in office, they roll back most of those pet projects and funnel the money back into the military budget.
You can more easily see the ups and downs on some of the charts here: http://www.usgovernmentspending.com/defense_spending
Think about that for a minute: if you put 30 random US people in a room, on average two of them will have served in wars!
Edit: you can also clearly see the rise of the military industrial complex in those graphs.
[EDIT] grammar
so "defense" spending was higher during wars, not really surprising and its peak was during Obama's term. Really doesnt fit the whole republican vs democrat theory.
I'd rather have national "high efficiency" healthcare. Think of how many medical schools, hospitals, and MD scholarships could be created with $112B. That's how you really "fix" healthcare.
