I can only think of one reason that a whole lot of single young men would be sent to another country and that is, because they are all Muslin, to take over the country by marrying up to four woman and along the way rape as many as they can. The point to this is to stop the men in the target country from having babies and making sure that as many of the women there only have babies from the Muslim men, With this policy they can become the majority in a country in only a few generations.
