I would hardly consider Japan a "Western" democracy when it had an Emperor who was worshiped as a God. Your statement was quite declarative that we never built democracies. I gave a couple good examples of countries in which we did revert, or reinvigorate democracies. You may split hairs if you'd like, but I still submit that without the largess of the United States, as well as the blood we shed, neither Germany or Japan would resemble anything like the democracies they are today.
Given that this thread was discussing the anti-war rantings of a radio talk show host regarding Iraq, I think that it is a reasonable comparison. If that is a waste of your time, then so be it.
Again, the USA was able to reintroduce democracy to Japan and Germany and it was able to do so because both those nations already were familiar with democracy and the concept of it.
The USA did not have to build a foundation for democracy because a foundation already existed.
What I said was that we (the USA) have never been able to build into any nation the foundations for democract that need to be in place before a democratic structure can be built.
Lastly I blame the internet for the rude part. Tone does not translate well on the net. But that does not negate the fact that your version of Japanese history is way wrong.
