Could a worldwide dominion federation remain together?

How long could the hypothetical global British Empire survive?

No duration is given. Survival is made conditional on how it governs: oppressive rule would be unstable, while dominion autonomy and the absence of foreign sponsors change the causes and resources of rebellion.

The survival question is answered conditionally: oppressive rule would make the imagined world empire unstable, while local self-government would give its regions more control over domestic affairs. The proposed dominion structure reserves common trade and defence questions for a federal government. With every region inside the same state, the scenario also removes foreign governments that might supply a rebellion. German arms supplied to the Boers are used as the comparison: under the hypothetical world government, those suppliers would face sanctions and arrest. Rebellions are still possible in the discussion; the claim is that they would lack the same external support.
