Hope we are doing the same.

"British police are currently trying to monitor "thousands" of potential security suspects....."
Once Islam reaches a critical mass inside a country, a "liberal democracy" cannot defeat terrorism as long as liberals, leftists, and socialists are in charge.
What happens when there are more "security suspects" than police? This is a military tactic known as "swarming".
To defeat terrorism Western democracies will have to undergo dramatic and painful change. Because 20% of the population will always side with the "enemy" it will be a homeland war on two fronts as well as multiple theatres overseas.
Too bad they can't just kick them out of the country. But I suppose it's better to have them where they can be watched.
