What strategy did churchill suggest for keeping peace and stopping the growth of nazi power?

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.

i think it would be reparing roads
