Always like how people dismiss things before they’ve ever read them or seen them.I've read extensively on the matter, as well as being fortunate to be living during the period. You can exaggerate all you wish but the fact is that three-chord repetition-leather pants wearing-rockers played (excuse the pun) no significant factor in the wall's collapse.
Thoughg I'm sure that you'll go on G. Beck's show and assert this, ignoring the actual reasons.
Hmm. I think I've "read extensively" (on this particular subject, perhaps more than you?). I also was "living during the period." When you get testimony from Reagan-era appointees who worked on VOA who had
actual CIA data about the impact of western music (a topic we mine in depth in the film---which you haven't seen) and similar evidence from Soviet and E. German bureaucrats, not to mention statements from Gorbachev to Leslie Mandoki that rock was critical (course, can't trust him, he's a commie), then you might think twice before calling it exaggeration.
Then again, you've not read the book nor seen the film. You just "know." I think that's sort of what the "global warming" people argue---they just "know."
