Were was the war take place?

I think that many of the people who submit questions to this site really should be working on their English skills rather than asking questions about history. What war are your talking about? And even if you identify the war, your question should read "where DID the war take place?" not "where was the war take place?".
Anyway, WW I took place in Europe, and WW II was fought pretty much everywhere on Earth. Does that help?
