On the NewsHour tonight there was a piece about the upgrading or 'modernization' of the U.S. nuclear arsenal, slated to cost on the order of one trillion dollars over the next several decades. There has been no discussion in the presidential campaign, at least so far as I'm aware, about the absurd levels of overkill embodied in the current arsenal, and it appears that the issue has not attracted much Congressional attention either. This despite the fact that a number of informed analysts have concluded that the U.S. nuclear triad as currently configured makes no strategic sense.
ETA: IMDb reminds me that Run Silent Run Deep (1958) is a WW2 movie; it involves submarines, but not nuclear ones. But as we say on the interwebs: whatever.
