America women get to fat and they complain too much
Some men cannot find a wife at home or they get lonely while they are away and relationships form. Many white women would not be happy with their husbands being away in the army and often foreign brides are happy to accept this for the security the mans money brings her.
They are scrony dorks that can't get white girls, so they find a Korean that wants to be American
Because Asian women are beautiful and any beautiful woman is going to attract the attention of a White Soldier.
