I know this may sound like a stupid question but did the UK's side win the 1st or/and the 2nd world war?

Why they most certainly did "win" in both wars.

Thank God for that =] I needed to find wars britain won recently and I could think of any

The Falkland Islands skirmish with Argentina was a bit more recent.

The Faulkland Islands and Dessert Storm.

It's okay this was for a project that was like months ago, thanks anyway!
