Germany, for its part, was forcibly created by Bismarck out of numerous smaller states in the decades leading up to 1871 and democracy did not emerge until after World War I—only to be snuffed out starting in 1933 by Adolf Hitler. Out of the post-war rubble emerged a West Germany that was democratic and an East Germany that was not. A unified, democratic Germany was not created until 1990.
As for Italy, it, too, did not emerge as a unified state until relatively late (1870). And it, too, saw its nascent democracy usurped by a fascist (Benito Mussolini), and it did not become a true liberal democracy until after World War II.
Nor was the process of democratization painless in the United States: It took two outright wars (the War of Independence and the Civil War) to establish self-government and another period of violent upheaval (the Civil Rights era of the 1950s-60s) to realize the potential of the Constitution.
Considering the tribulations suffered by the U.S. and Europe on the road to democracy, it is hardly surprising that the process of political reform is proving painful in the Middle East.
