L'arriviste said:I don't like this nationality argument because it doesn't really lead to an appreciable outcome. In terms of US riders within the same European pro circuit as Spain, I guess at five positives / admissions of banned substance use. Not counting actual sanctions, amateurs or US/Latin America circuit.

Subject to the constraints, did I miss any?
There would be no need for a nationality argument if the national federations would cease being complicit in the cover-up.
Look at France vs. Spain. I really do believe that the main reason French cyclists have not been as successful as Spanish cyclists or some other nationalities is that France has a much more aggressive anti-doping program.
