Wow, people think that "time-travelling" is not possible? I do listen to old albums from 1984 (e.g. Siouxsie & the Banshees, The Cure, Echo & the Bunnymen) and when I see this (new) fear of a nuclear war, I really do feel like I am back in the "good old" cold war 1980s!
(And btw, with all this, some people wondered why young folks would turn to (post-)punk, new wave, goth and other "dark music" or carry slogans like "no future"? Oh my...)
