This is the first time I have seen the term "fifth column" used in relation to Moslem extremists, and it is appropriate now. In the last two world wars, fifth columnists were rounded up and interned for the duration of the war.
Many, perhaps most, were innocents but that was the price they had to pay for the safety of the larger society. That is what is coming next for whole Moslem communities in The West if they continue to harbour their extremists.
