It's not a podcast, but one of the better/only good uses I've found for Twitter is some of the folks on there that will "live tweet" WWI and WWII. It's a pretty cool daily feed of what happened on that day as they progress through the war. Walking daily through the war from start to finish in order is pretty cool.
“Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy. It's inherent virtue is the equal sharing of miseries." - Winston Churchill
