I am not very sure its so sad not to have gained any medals when we talk about small and/or impoverished countries like Bolivia and Cyprus, or countries in turmoil like Iraq and Syria and others like them, who do not afford to spend money and/or time for the promotion of athletics. Especially when such small and/or poor countries are compared to rich and/or powerful ones which have turned the promotion of sports and the improvement of the performances of their athletes into an industry (quite dirty at times too). For me, even the qualification to the Olympic games of athletes from small/poor/troubled countries is a commendable achievement to be attributed mainly, if not solely, to the athletes themselves and their own determination and their own efforts.
After all, isn't the spirit of the Olympic Games the getting together of the Nations of the World? Or isn't it?
