Assuming that my belief is correct one can only hope that there's a valid scientific basis to that rule.I do wonder,however,what blood donors who've lived their entire lives in Europe do.
Or how about all those American military stationed in Germany up until the fall of the Warsaw Pact and then the USSR?
Remember the Mad Cow scare didn’t start until years later, after 9-11-2001, as noted.
Or maybe.....banning U.S. vets serving there 1980-1990 was a sop to the homosexuals who are also completely banned.
I sense a tit for tat, if you get my drift.
