Regarding your second paragraph, I think you may simply have a chip on your shoulder. My comfort with a German domain name is based on my knowledge that Germany's been a stable democracy for the last sixty years. I know very little about South America and am therefore more leery of domains backed by governments there.
I am quite fond of the UK and France, but given the curious libel and intellectual property legal environments of those two countries, respectively—yes, from my American and therefore evil, small-minded perspective—I wouldn't want to expose my business to those environment by using a registrar in the UK or France.
So sorry to not be the racist cultural-imperialist Europhile you'd like me to be.
