Well, *they* did strip Germany of its colonies in the Treaty of Versailles, iirc.
Imagine it’s 1935....you have to choice to support one country against the other.
Country A: Desires colonies in the East, but makes no claim on any British colonies or interests.
Country B: A country whose stated goal, is working towards the violent overthrow, and physical extermination of the ruling class in every country in the world.
Without the benefit of hindsight, which one would you support?
