That's still a huge amount. I too am in favour of "doing something" about Islamist extremism, but I don't have any good specific ideas and neither it seems does anyone else. We should learn more from the NI peace process; in some ways the new anti-extremism policy reminds me of when Gerry Adams couldn't speak on TV. It was stupid and ineffective then and unlikely to help now.
The first thing to do is to stop acting morally superior whilst bombing the out of any country that doesn't fall in line in the name of democracy. Anyone with even the slightest ability to think for themselves can see through this and views evil as evil regardless of the badge worn. Others unfortunately don't make it this far and either throw their weight behind such policies or resist them by joining the 'enemy'. These are the kids that went to Syria and honestly it's difficult for me to see them as any different as the kids that join the UK or US armed forces. They are naive and misinformed otherwise they would never consider joining any armed forces.
Second is to do everything possible to reduce the income inequality that is ever expanding in the world.
Thirdly we also need to focus on education and tolerance.
The current establishment has proven themselves to be inept on all three counts. No other tactic has any chance of succeeding.
