Martin Scorsese plans to direct controversial film set in Japan

From the AP:

Martin Scorsese has disclosed that he is planning to direct a movie, set in 17th-century Japan, that may have implications related to the war in Iraq. In an interview with the Associated Press at the Cannes film festival, Scorsese said that his film, Silence, presumably based on the novel of the same name by Shusaku Endo and William Johnston about Portuguese Christian missionaries who arrived in Japan in feudal times, has parallels to America's role in Iraq. The Oscar-winning director (The Departed) said that he hopes to shoot the film in Japan, at least partially, beginning next summer. "It raises a lot of questions about foreign cultures coming in and imposing their way of thinking on another culture they know nothing about," Scorsese told the A.P.

So was it a mistake for the US and other Western countries to invade and occupy Afghanistan and impose their culture of democracy in that god-forsaken terrorist sponsoring state?

Is Scorsese saying that the US and NATO should get the hell out of Afghanistan now and leave the weak Karzai gov't to fend for himself against the Taliban and Al Queda?

What about Japan after WW2? Was it a mistake too for the US to impose democracy in that part of the world then?

I like his movies, but Scorsese sometimes make dumb political comments.
