violence shouldn't be needed, but it needs to be possible at all times. it's a great equalizer of sorts. as the islamists have shown us time and time again, a small number of fighters willing to die can cause enormous damage. the mere possibility of that happening will, or should, restrict politicians from passing extreme laws. the problem here, however, is that politicians and the rich are well aware, and deliberately create and support terorists to mislead these extremists into attacking the wrong targets. whether that's a jewish banker getting rich of insuring the wtc, or the us funding kurds so they attack syria instead of turkey. however, the mere risk of lone wolves still acts as a deterrent. go to a political meeting of your ruling party and listen to what they say, then look at what they actually do. those things are worlds apart. because, for all their posturing, they know that if they move to fast, there might just be that one fanatic who'll come visit their homes.
