For many contemporary observers, the Spanish Civil War was seen as very much of a piece with the war against Hitler and Mussolini. But then things changed. Why?
Spain couldn't form a government after its last election, so it had to try again. And it looks like the radicals are shut out.
Parliamentarians have again failed to form a coalition, nearly three months after the election.
Populist politicians are on the march, first in Latin America, then in Europe and the US. They are on both the left and right, and their policies vary, but their approach carries the same risks.
