I think they should be in Sweden. That way they will only have a few hours to eat around Midnight. When Ramadan is in the Winter, I'd want them to go to extreme Southern Chile for it. The more daylight hours for Muslims during Ramadan, the more they starve. Maybe that would send them the message that Islam is not compatible with all countries and was originally invented at a lower latitude.
On the other hand, if they stay in their own countries for Ramadan, they will more likely dehydrate in the desert Sun even though they have earlier Sunsets there.
