We may be in the era of Facebook and fracking. But 2013 is still beginning to look a lot like the cataclysmic century we just left behind.
More people probably died from the wars of the 20th century than from the battles of the prior 2,500 years combined. The bloodiest century saw the rise of fascism, Nazism, communism and jihadism.
Capitalism almost collapsed during the Great Depression. What followed was a Big Government antidote not unlike our own experience after the panic of 2008.
The end of most colonialism and imperialism was also a 20th-century development. So was the rise of modernist and postmodernist culture, along with civil rights, feminism and nationalism.
No wonder that despite the promise of the 21st century, we keep trying to make sense of the last 13 years by looking back through the lenses of the last action-packed 100.
Take the present chaos abroad. The rise and new assertiveness of China is eerily like that of Japan in the 1930s.
Japan also once tried to adopt Western-style industrial capitalism without consensual government. For a time, that nation grew rapidly.
The rising sun of Japan felt slighted by the supposedly weak and corrupt twilight Western powers after World War I. America and its European allies were not willing to grant Japan regional influence commensurate with its rising global power. What followed was a decade-long Japanese war in Asia.
Does the same depressing lesson now apply to China? Can Beijing square the circle of capitalism without democracy? Can it have much of the world's cash without the world's largest military?
Will China, like 1930s Japan, resent established Western powers to the point of another war in the Pacific?
The situation in Syria seems a lot like the Spanish Civil War of 1936-1939. Almost every regional power and world superpower is flooding Syria with either weapons, troops or both -- Iran, Hezbollah, the Gulf sheikdoms, Russia, Europe and the United States.
Syrian President Bashar al-Assad is a sort of Franco-type thug, propping up his fascist effort with foreign arms and troops. If Syria follows the Spanish blueprint for a wider war, what follows will be even worse.
Talking loudly while carrying a small stick became infamous last century, after the British capitulation to Hitler at Munich in 1938. The same sort of "peace for our time" complacency characterizes Western sanctions in response to Iranian nuclear proliferation.
