In an interview for Game Hunters, Mark Lamia, Treyarch’s studio head, explained why the action in the game takes place after WWII and during the Cold War:

"This setting, this period, was perfect for us because it allowed us this creativity. This period hasn't really been done in games and it spans a period of time. We are not getting into the exact period of time, because it is part of our story that we are going to reveal later, but it does cover a longer period during this era."http://content.usatoday.com/communities/gamehunters/post/2010/05/more-on-call-of-duty-black-ops-with-treyarch-studio-head-mark-lamia/1A demo level for Call of Duty: Black Ops was shown to Game Hunters during their interview.
