We talk with the host of Dan Snow's History Hit, the no. 1 history podcast, about some of our favourite subjects.  Does history help us understand the present state of politics, and which history?  Are we closer to the 1890s, the 1930s, or the 1980s? How should we commemorate the aftermath of WWI? Plus we talk about whether Chinese politicians are really able to take the long view. With Helen Thompson.
