Probably the most interesting aspect of Churchill's life in politics in the 1930's is how much you can see the hand of the DS in Great Britain before the war. Otherwise, I think they would have been much better prepared to deal with Hitler. Churchill was constantly sounding the alarm about Nazi ambitions, yet the people in power always seemed to side with Hitler while making excuses about how it's best for everyone.
There's just so many parallels to today (and over the past 50 years) it's uncanny. You just have to blur the national boundaries and political parties - it's all there.
BTW, my knowledge of European history after WWII pretty much falls off a cliff.
