What was the most significant year of the 20th century? There are three plausible candidates. The first is 1917, the year of the Russian Revolution and America’s entry into the First World War, which set in train a century of superpower conflict. The second is 1918, the year that saw Russia’s exit from the war and the defeat of the German and Austro-Hungarian Empires, which set the stage for the triumph of democracy. The third is 1919, the year of the Weimar constitution and the Paris Peace Conference, which ensured that the triumph would be squandered.

Syria has for now turned into the war that never happened thanks to the gaffe that never was. Once John Kerry let slip that there was something Assad could do to head off a military strike – agree to international oversight of his chemical arsenal – the stalled march to war became a headlong retreat.

But she is a lot more relentless: if anything, she keeps chopping and changing long after they have gone home.

Casting around for kindred spirits in the blighted international landscape of the 1930s, Hitler looked fondly towards Dixie. What was not to like? The South was effectively a one-party state. In the 1936 presidential election, FDR’s Democratic ticket won 97 per cent of the vote in Mississippi, 99 per cent in South Carolina. In some counties no votes at all were recorded for Republican...

American democracy is an amazing, fascinating, bewildering thing. There has never been anything else like it. Even now, as democracy becomes an ever more familiar feature of our world, there is still nothing like the American version. During the early years of the American republic, in the first half of the 19th century, what fascinated outsiders was its sheer implausibility. Could you...
