The Solheim Cup has no relevance to current women's professional golf. When originally conceived the US vs Europe was meaningful. Currently excluding Asian players from the vs team is just a method trying to keep the USA winning.
A better formal to have relevant competition would be to combine the USA and Europe against the Asian players. I suspect such a format would be an old fashioned ass kicking with the USA and Europe providing the ass.
Currently it's kind of like the Patriots playing Alabama.
