Hey, Canada has been invaded by the US on at least three occasions -- Revolutionary War, War of 1812, and the Fenian Raids. I don't know of another country with a 3-0 record against the US.
Canada wasn't an independent country for any of those (particularly the first two and the beginning of the third), and wasn't a component of the country that won the first of those.
It was not a shining example of successful intervention. It may or may not have been a "shining example" - in the sense of an example that is good as an example - of a tendency toward attempted intervention.
