During the early years of the IRA terrorism, the British government covered it up in the media and had a ban on anybody from the IRA ever appearing on TV. The government also told people to just carry on as if nothing happened. The result? The IRA bombing campaign got worse and worse and closer and closer to London, until one day morters were landing in the garden of Number 10 and the business district had been blown up. 

To combat terrorism you must absolutely define it and speak of it. The IRA bombing campaign only ended when the British government, because of heroic politicians - John Major and then Tony Blair - took the very personal and political risks to bring the parties to the table and make peace. This was done and could only succeed with the security services and the military working harmony to keep the pressure on the terrorists. We need to do this with radical Islam. And we need to chuck out the quisling politicians and the cowards.
