What does that mean??  How can someone be "international"??

Hey the World League hasn't started yet!!!!!

1. hold dual (or multiple) nationality
   
2. are stateless (perhaps the country they used to belong to has ceased to exist)
   
3. don't accept or recognise national boundaries
   
4. not sure which state they are a citizen of
   

To be only an international person is a nice idea

You don't have to pay taxes anywhere.

 Maybe we ought to start an internationalists political movement and do away with all these (mostly-criminal) governments and borders and etc etc etc.....

Lol... 

You're very well informed!

If everyone joined the International team: who would they play against?

 Aliens?

good question.  aliens maybe?
