This a powerpoint on International Relationships 1919-39, including the Treaty of Versailles, The League Of Nations, and the collapse of international peace. There's a (pretty detailed) slide on each focus point from the specification - except the last question/slide, which is blank, but you can probably figure it out from the other info provided.
There's also some useful links to revision websites on there.
I hope this helps you guys! Feel free to comment/ask any questions/whatever.
