Britain has been to war in America, Asia, all over Europe, including her neighbours Scotland and Ireland, not forgetting her conflicts with the naives of Australia and New Zealand. Post 1945 we have a few other to add to the list, there may be some others I may have missed,
India,Palestine, Malaya, Korea, Suez Canal Zone, Kenya, Cyprus, Suez 1956, Borneo, Vietnam, Aden, Radfan, Oman, Dhofar, N Ireland, The Falklands, The Gulf War, Bosnia, Kosovo, and Sierra Leone.

Now would some kind person from the US try and fill in the countries the world`s policeman has smashed up.
