I heard about Arms Control Wonk Podcast on This American Life. It is exactly what the title suggests. Its selling point is that the hosts break things down very clearly and frankly.  So frankly it will scare you.

I don’t understand more than half of what they are talking about, but I enjoy that. I love some lingo and they have it. The hosts know what they are talking about it and they enjoy talking about it. Which would be fun, except this is about nuclear weapons coming from North Korea towards the US.
