Queen Victoria confronts a future World War I

If Queen Victoria could see World War I coming, what might she do to prevent or shorten it?

She could use her formidable family authority to remove or restrain Wilhelm II, protecting the liberal-monarchical European order she and Albert hoped to build.

A playful scenario imagines Victoria summoning Wilhelm II and dealing with him ruthlessly. Beneath the joke is a political point: Victoria and Albert envisioned a peaceful Europe of liberal monarchies linked through family and diplomacy. Wilhelm's course ran against that project, while World War I would destroy much of the order they hoped to preserve. Foreknowledge would therefore give Victoria a strong motive to use her family authority against him. Dynastic influence becomes a possible intervention before mass war made that older system irrelevant.
