I have heard that: because so much of the world has entered into Free Trade Agreements with the USA - it means that most of those countries that have
done so also had to adopt Intellectual Property laws that are in-line with the American ones to do so. So on this basis, should the US pass SOPA/PIPA,
the nations with a FTA with the US would soon follow suit with similar/equivalent laws.
So yeah.
EDIT:
Up until such a time, I don't think the US would worry about extraditing 15 year olds who upload copyrighted material, it would be too expensive.
The whole copyright system should be abolished in-favour of Creative Commons. Have you seen "RiP: A Remix Manifesto"
