I agree with you. It can't be stopped. It will unfortunately happen.
The only positive thing about such terrorist attacks is that they openly demonstrate to a largely ignorant and misinformed populous, the danger that Islam poses to the west. Such attacks expose the true goal of Islam - to dominate, subjugate and to terrorise the non-muslims. Islam's goal is to enslave the whole world. It is written down for all to see in the Koran. It is hiding in plain sight. Yet no one in the media seems to have the courage to say so. I wish that just once, a journalist on live TV would ask a muslim spokesperson, "What is the punishment laid down in the Koran for insulting the Prophet?". If the interviewee objects or refuses to answer, the interviewer should just simply "Paxman" them - keep repeating the question until such time as an answer is given or the allotted timeslot expires. It would be very revealing.

The actions of these murderous lunatics should be a wake up call to every non-muslim in the world. But even now, the contrite excuses are being formulated and expressed (assisted by a complicit and cowardly media) to re-label these murderous religious fiends as "fanatics" who have "warped" the meaning is Islam. Nothing could be further from the truth.
