may I compliment you on a much better quality and factual post !
devil is in the detail though.....the US interest is in defensive measures ......the US don't wish to use space weapons to attack another country- or for other copuntries to be allowed to ither , but they don't wish to be prohibited from using devices capable oif stopping incoming missiles - the so called star wars technology .
the russian interest is in having free passage possible for their incoming missiles and so seek to have air(space) defence prohibited .
