Answer:
stay neutral
Explanation:
Great Britain was torn between taking action (or in this case inaction) in the war so that slavery would end, or so at least they wouldn't appear to be supporting it, and openly supporting the Confederacy, helping to split a potential and growing rival in two.

United Kingdom and the American Civil War. The United Kingdom of Great Britain and Ireland remained officially neutral throughout the American Civil War (1861–1865).
The British elite tended to support the Confederacy, but ordinary people tended to support the United States, the Union or "the North".
