Falcon 1 doesn't move the needle on SDI either, except insofar as it was intended as a developmental stepping stone towards a reusable rocket (which it was publicly claimed to be.) Vulcan isn't, SLS isn't... Blue Origin's work is.
Now, you said that even Atlas rockets developed after 2003 are technically advancing an SDI agenda. I don't know which Atlas rocket you're talking about (Atlas V Heavy development?), but it definitely isn't true. There was never any pretext of the Atlas rocket family being a step towards reusability, and therefore it has nothing to do with any serious SDI proposal.
