On one hand, US policies often have global ramifications (although I'm cynical enough to think that nothing a petition here will affect will have enough importance to matter in that respect). Also, it's often useful to get the perspective of people in general, wherever they are in the world, in case there's some sort of general consensus (although it would be a consensus of educated internet accessing elites in many parts of the world...)
On the other hand, it's a site for the US government to solicit information from US citizens. People from other countries registering their opinion doesn't really fit all that well with that goal.
Hope you get it up to 100k. Good luck!
