If you are referring to the 1930s I don't think Churchill had a clear strategy of the kind that you suggest. He would have opposed most breaches of the Treaty of Versailles, which it is unclear what he would have done if Hitler had defied British protests. Most of Hitler's early aims focused on Eastern Central Europe, where British influence at the time was almost nil.
Nationalism was a huge cause of World War 1. Nationalism meant that a country was very proud and wanted to be the best which leads to greed, false hopes, and aggression. Militarism was also a big part because countries were part of an arms race to have the biggest and strongest navy and military.
