It's still strange to me. maybe it's because i'm patriotic and couldn't imagine playing under two different flags depending on the event but it's still odd to me
It's perfectly normal for an immigrant to be patriotic about both his old and new countries. Especially in this case, since his old country is a far different place than the war-torn country he left as a 14-year-old boy. (Fleeing a war zone does not mean that you don't still love your country - it's just natural self-protection - or that you don't love the country that took you in during your time of need.)
In any event, looks like our buddy is scheduled to play both singles and doubles, with singles matches against Frederico Gil (#83) and Rui Machado (#124). Not easy matches, but let's hope for some good results to boost his confidence for a strong tour comeback!
A win for Bos-Herz (an uphill battle, for sure) would promote the team to Europe/Africa Group I, which would be awesome for national pride in a country still reconciling from an ugly civil war.
