History of successful democracy?

Question

When (in the history of any government) has democracy been successfully exported/imported through means of armed war or armed occupation?

Why was it successful in (your given) instance as opposed to unsuccessful attempts?

Answer 1

Japan and West Germany (now all of Germany), Austria and Italy. Germany and Italy were run by fascist dictators prior to the end of World War Two and the allied occupation. Japan was run by military war lords, using the Emperor as a front man. Austria was a fiefdom of Hitler's Germany from 1938 to 1945.
It was successful because all people want two things: economic freedom and political freedom. In that way they can provide a better life for their children then they had for themselves. Or, in the words of the Preamble to the U.S. Constitution: "to secure the blessings of liberty to ourselves and our posterity".
If the occupation is benign, the end of the occupation will leave both the occupier and the occupied with a sense of a job well done. In the case of the United States, all of the territory occupied outside the states from armed invasion or war have been returned to the native people of those lands, with the exception of Guam, Puerto Rico and American Samoa.

Answer 2

For democracy to be successful it has always had to be locally established rather than imposed by war.

Answer 3

Ask Japan.

Answer 4

because it felt like being succesful.
