History and hindsight seem to share a clarity denied to those who lead us these days. The impression of precision-guided bombs which can surgically eliminate problems has been well and truly debunked, as has the folly of trying to impose western values on alien cultures. Its all happened before, and the British were heavily involved, for better or worse. So what to do now? Well, as far as the UK is concerned, there is not a lot we can do. Like it or not we just don't have the military clout any more. So probably best to do as we are doing, and join in a multi-national effort to crack down on these criminal thugs and their atrocious conduct. What we must do, though, is demand that this foolish coalition government change its defence policy now, and start to rebuild the nation's defences which they have so wantonly slashed. We must also crack-down on extremism at home and support the police, military and the courts in taking rigorous action against offenders, especially those who come back from having committed vile crimes abroad, no matter what their so-called justification.
