“Where there are NO Muslims there is NO terrorism.
Life and Islam cannot co-exist. Choose.”
So the answer is right there in front of all of us isn’t it? And if we don’t get them, they will manage to get all of us. Where there are no Muslims should be the entire world. You can’t simply try to confine them to some area and think that they will not find a way to get out.
Japan has few Muslims, if any. I don't think it has any mosques. It's an advanced country with many travelers and tourists.
