Where was most of World War 2 taken place?
North Africa, Eastern and Western Europe and the Pacific. Mostly Europe.
Yes-Most peoples don't have to worry (or stress out) about "mush-room clouds" (atomic bombs going off) suddenly appearing out of no-where anymore. No-Terrorists have taken their place. At least during the cold war, global security was so concerned about "the cold war", terrorists were unable to communicate with each other...if they did communicate with each other; THEY would have been taken as part of the cold war (they would have been caught up in it).
