I think the majority of credit should be assigned to you. You clearly acknowledge that your learning is multinational and thus not evidence of the exceptionalism of the specific country your discovery occurred in but evidence of YOUR (and your teams) exceptionalism which has been facilitated by many nations regardless of the ultimate location of the discovery.

Take the story of Newton and the Apple, (I know its probably not accurate historically, but bare with me a moment). Are we concerned with if Newton was in London/Sicily/Barcelona/Paris when the proverbial apple fell? How about who owned the apple tree? No, the observation could have been made in any location. The variable which caused the "innovation" was the observer, not his location.
