The US was economically beginning to be involved on the world level, but wasn't really a "power worth considering" until after WWI, partially just because of distance.
yeah, this was really my point.
A (maybe terrible) modern analogy is how concerned would we be with a civil war in say, South America, where a significant chunk of our lithium comes from? We would probably be concerned, but our economic and military clout means that we would always be the customer for whoever won that civil war.
