According to a brand new report from the Center for American Progress (a report we're proud to have recently sponsored):
A 2013 CATO Institute policy report sponsored by Ploughshares came to a similarly emphatic conclusion: "In fact, nuclear weapons are essentially irrelevant in actual US wars, which are against insurgents and weak states without nuclear arsenals," arguing for a shift that "would facilitate major reductions in the nuclear arsenal, the elimination of at least one leg of the triad, and substantial savings."
The Department of Defense plans to modernize all three legs (strategic bombers, ICBMs, and submarine-launched ballistic missiles) of the nuclear arsenal at once, while modernizing conventional forces as well. According to a report by the Center for Strategic & International Studies (another report we're proud to have recently sponsored):
Ploughshares Fund believes that inefficiently spending a trillion dollars over 30 years on weapons that are outdated, overpriced and unnecessary is a bad idea. We also believe that strategic insights and bipartisan policy solutions from the best organizations and smartest minds striving to make the world safer and more secure by reducing the enormous threat that nuclear weapons pose to humanity — is a great idea, perhaps even an idea that could change the world.
