Hi Dennis,

Thank you for your reply,

True about the disaster for radio, and yes, reguarding this treaty, the US would probably not back away from it even others already have.

however it is also true that international law is a perception, not a reality. Countries only abid by it when it is in their interests. by that i mean the peoples interests... Thus there is no authority that can truely enforce it.

Rich:
The U.S. would not do this for it would not only cause disaster in the
radio law but would set a presedent that the US for business gain woud frogo
international law..
