yea, why not?
at least the WBC...
I would say why not the olympics, but there's no baseball in the olympics anymore...
but international competitions for minor leaguers such as the world cup would be fun... and would be another different kind of game experience managing a national squad...
This would be similar to how the real life major league clubs contribute eligible players to the Arizona Fall League teams... So international competitions could also come into play as new depth for minor leagues, in addition, of course, to the World Baseball Classic element.
