Why an 1880s German-American alliance would unravel

What if Germany and the United States formed a full alliance in the 1880s?

Britain would view it as manageable because German and American interests would collide, while US ratification made a formal alliance unlikely.

In the 1880s the United States had not yet developed the naval strength that would make the partnership immediately threatening to Britain. Germany and the United States also competed for influence in the Pacific and South America, creating repeated opportunities for their interests to collide. Britain could exploit or simply wait for those crises to strain the agreement. A formal alliance would additionally require congressional ratification, so the panel finds a limited non-aggression pact more plausible than a durable treaty.
