All the more reason to limit the number of Muslims allowed to enter a country - at the very least, limit those that embrace the militant aggressive form of Islam that is 100% incompatible with Western values and human rights. Certainly don't offer preferential treatment to them as potential immigrants as currently happens.
Japan has taken notice. That's why she won't accept Muslim refugees.
She didn't care what anybody said at the time. Still doesn't. Now she watches relatively peacefully while those that criticized Japan's stance are having to deal with the problems.
