In descending order of importance I'm a Yorkshireman, Earthling, British and European; you don't need to be American to appreciate that the result of the efforts by USA, NASA and Space-X, culminating in the events of the last 24 hours, is awesome.
That said, like any meaningful endeavour, I'm sure that they would be the first to say it would not have been possible without the pioneering work and professional-bond of all space-fareing nations and organisations and, sometimes, the sacrifices of their crews.
