At what point in history did nations in Europe (particularly Britain)

1812

WWI

Another important question, Hawg, is how many unarmed WWII era marines it would take to defeat a chimp? A silverback?

World War I. But we weren't fully respected and viewed as being needed until World War II broke out.

Well, it was a gradual process and it started before we were even a country. First European countries recognized how rich the Americas are in resources. They knew whoever dominates this region would be among the richest countries in the world.

Then with the American colonies victory in the Revolutionary War and War of 1812, Europe got the message that the US can be a potent military opponent. Our war against the Barbary Pirates showed we can project power beyond our shores.

Our rapid and acquisition of territory westward during the 19th century also served notice to Europe of the fact America was now a major world power. Along with our geographic growth came economic growth. From King Cotton in the South, the whaling fleets in Nee England from the early 19th century onward America’s potential was clear to anyone paying attention.

What cemented our position as a not only an economic but also military world power though was first the Civil War in that it showed Europe that not only was America able to created a massive military machine capable of military operations on a continental scale, it was able to crated two (Union & Confederate) such military machines and sustain them for years at a time. This served notice to Europe that America possesses military potential none of them except Britain could hope to match.

The final step in the world seeing America as a major player was our defeat of Spain in the Spanish-American War. This war is what gave America its own respectable colonial empire. This fact, along with the Great White Fleet which showed thr world America was a major naval player capable of projecting substantial naval power across the globe served notice to Europe that America was a force to be reckoned with.

A little while after the civil war probably. I don’t think a lot of people realize it, but we already had the world’s largesf economy years before WW1.

England, Britain, is not European.

The Irish, Scots, Welsh are, however.

This is historic, and has nothing to do with brexit.

After/During the industrial revolution. We were inventing things the world could never imagine at a rapid pace and they had to see that we could use that advantage in military applications. Which we did not too long after

I think during the post-Civil War period there became a realization of America's economic and industrial might. Especially among the landed European nobility who were becoming increasingly cash poor. The robber barons in America were either outright buying these estates or stripping them of their art, furniture, etc.

But I don't think the European political and military classes held America in quite the same regard yet. By the lead-in to WWI, though, I think both sides in Europe knew that America was a game changer.
