But the fact is, they lost. Making an unfair treaty because that's what someone else would have done to you doesn't make it justified. They are then stooping to the level of unfairness as Germany regardless of whether Germany would have done the same or not. It is still neither justified nor fair.

No 4 whereby all countries were to reduce military power. The treaty only made for Germany to reduce military power leaving it defenceless over other countries whose strength remained the same. This defeats the point of disarmament as it was not equal.
