1. Avoid Germany get the whole blame regarding the war and make every Central Power responsible for it. Therefore, the indeminizations and war reparations is shared by all central powers.The amount of Germany had to pay for the allies left the nation defenseless in economical crisis and was a major factor in the hyperinflation of the 1920's.2. Avoid France occupies the Ruhr industrial area. Not only that exacerbated the german revanchism feelings but it ignited the popularity of the nazis.-I would diminish the hard conditions on the german military. That being, the prohibition of having an air force and submarines. This was a big blow on Germany's pride and was seen as an humiliation which of course was used by Hitler on it's favour. 3. Avoid confrontation at the Society of Nations. By that, I would have enabled both the USSR and Germany to become members if they wanted. By approaching Germany into become a friend and not keeping them as enemies I think not only Weimar Republic would have survived but also it would have diminished the popularity of Hitler.
