During this period the United States was isolationist after the end of W.W.1 and wasn't very concerned with foreign affairs in Europe. And while Britain still maintained an interest in continental Europe due to the virtue of its sheer proximity to it, it was more concerned with the maintenance of its empire. This included dealing with stronger anti-colonialist sentiments and growing independence movements, such as the Indian independence movement. Only when Germany began to be more hostile in 1933 and started rearming did the UK begin to focus on Europe, chiefly by creating new alliances(such as with Poland), appeasement to stave off immediate conflict, and a slow rearmament of its own military in order to deal with future challenges. In short there was no concerted Anglo-Saxon European Balance of Power Strategy due to the aforementioned. As well, the interwar period was unique in the fact that there was no need for an enforced balance of power as almost every European country had been left weak from both World War 1 and the Great depression, thus leaving no dominant or even belligerent power in Europe save the Soviet Union and later Nazi Germany.towards the mid to late 1930's.
