The US used to run rampant over other's intellectual property in the 1800's
That's a common myth. One person, samuel slater, memorized the designs of textile factory machinery as an apprentice to a pioneer in the British industry before migrating to the United States at the age of 21. https://en.wikipedia.org/wiki/Samuel_Slater US didn't steal anything using Samuel Slater.
I haven't heard of any other examples of US stealing intellectual properties in 1800. Plus, that's over 200 years ago. Would you like to bring up the something more recent?
