It's utterly and completely disgusting isn't it MD. Yet, as WM says, those who worship the religion and do not deny or condemn the extremism or the murder committed in the name of that extremism, are complicit in that murder. That makes this a religious war and that makes anyone who supports this kind of action (either by agreement or inaction), culpable of the actions.
The Israeli's have a bombing campaign to try and stop thousands of rockets being launched at their civilians. They try to only target military objectives, yet fail because this same contempt for civilian life is rife in extremist Islam. They are denounced to the ends of the earth by Christian and Moslem alike.
IS murder their way across Iraq and Syria. In the name of Islam and the right of Islam. Condemned by Islam? Dear me no. Lots of silence. Even when they murder hundreds of women and children. Turkey even makes support for air strikes conditional on action against the Syrian regime.
The stated goal of IS is a rampage of murder and atrocities to "regain" the lost Islamic Caliphate. They don't care. They'll murder anyone and everyone to get what they want and they won't stop until they are stopped. In the long run they will cow every town village and city they come in contact with.
There is a precedent for this. It is Vietnam. During that conflict the Americans had their "hearts and minds" campaign. On the other side it was murder your wife and rape your daughters and take your sons to fight in the war. We all know who won that one.
Except that the final analysis the only thing lost was a backward country thousands of miles east of anywhere anyone cared about. If we lose to IS, we lose Turkey, Spain and all of North Africa. Plus the war with Israel would go Nuclear in the final battle.
So what do we do? Bomb a few people on the ground? There are millions more there waiting to be impressed. Or do we fight the fundamental basis of the murderers and make them a pariah in their own back yard?
That's the problem with wars. They leave us the worst of all choices.
I've offered one.
The alternative is two fold.
Put tens of thousands of our own troops on the ground. Fight a war, expensive in lives and equipment for two years. Win the war and then spend hundreds of lives over the next 10 years trying to police a bunch of murdering scum. Only to leave with out tails between our legs, ten years later, having failed and sick of the cost in lives. We've never done that before have we???
Give up and let them get on with it. But, of course, you'll need to give up your holidays in Spain. They won't allow people sunning themselves on the beach and who wants to go to the beach only to be wearing more clothes than we would to work at home??? In temperatures we wouldn't even want to wear a swimming suit in.
We can make this kind of conquest so expensive to the religion that the general population will stop hiding and supporting them. Or we can just let them get on with it.
All we are doing right now is setting the scene for chaos and misery for millions of people. Followed by a 7th century regime of misery and murder over hundreds of millions of people.
All I ask is that you tell me what you would do to stop these people. I've had my twopence worth. I'd hate to have to do it. The threat might even be enough to stop most of it. I'd also support the Syrian government forces to defeat the rebels and stabilise Syria, leaving these scum nowhere to go.
So what would you do to save the millions of lives it's going to cost?
