When Communism fell in 1989, the temptation for Western commentators to gloat triumphantly proved irresistible. This, it was declared, marked the end of History. Henceforth, the world belonged to liberal capitalism - there was no alternative - and we would all march forward in unison towards a future shaped by peace, democracy and free markets. Twenty years on this assertion looks threadbare. There can be no question that the fall of the Berlin Wall and the domino-like collapse of Communism states from the suburbs of Vienna to the shores of the Pacific marked a very significant transition: one in which millions of men and women were liberated from a dismal and defunct ideology and its authoritarian institutions. But no one could credibly assert that what replaced Communism was an era of idyllic tranquility. There was no peace in post-Communist Yugoslavia, and precious little democracy in any of the successor states of the Soviet Union. As for free markets, they surely flourished, but it is not clear for whom. The West - Europe and the United States above all - missed a once-in-a-century opportunity to re-shape the world around agreed and improved international institutions and practices. Instead, we sat back and congratulated ourselves upon having won the Cold War: a sure way to lose the peace. The years from 1989 to 2009 were consumed by locusts.
